It’s no different with blogging. Less than 1 % earn really good money out of it. Ramit Sethi, for example. Then there are some people who are making a decent living out of it. But the vast majority of bloggers earn zero dollars. The statistics suck, but that’s the name of the game, if you want to earn money with fame. You must get in the top 10 %, or even better in the top 1%.
After listening to your show, I found a lead to my first side hustle. For my wife’s program and mine, we are required to have CPR. We took our class to meet these requirements, and I talked with our instructor who passed my name to the owner letting him know I was curious about becoming an instructor. I was contacted about certifying myself to teach classes! – John S.

The first batch of natural experiments concerns understanding the effects of isolation and of group size and of communication with other groups on the productivity of human societies. Let's learn from the extreme examples of isolation of human societies. If isolation has any effect on human societies, the places we're most likely to see that effect are the histories of those two islands off southeastern Australia called Tasmania and Flinders Island. They lie about 200 miles off the southeast coast of Australia and are separated today from Australia by Bass Straits, but those straits are relatively shallow, so their floor lay above sea level at glacial times of low sea level up to about 10,000 years ago. The Bass Straits between Tasmania and Australia were then dry land, and Tasmania was part of the Australian mainland, just as Britain used to be part of the European mainland. When the glaciers melted, sea level rose and cut off Tasmania from the Australian mainland. So when Tasmania and Flinders were part of the Australian mainland, Australian Aborigines walked down to Tasmania and Flinders from the mainland.         
I am hoping my success story involves a combination of the blog and consulting. I’ve been really struggling with the consulting lately in an attempt at networking and obtaining more clients. Between the two blogs, keeping up with industry, and maintaining an amicable family relationship I find I am short on time. My wife has not worked for over 2 years so we are on a single income. We do have a child who takes a lot of time and money.
Keep in mind though, you don’t need a website to do sponsored content since you can also get paid if you have a lot of social media followers. My wife has a pretty big Instagram following, and she gets all kinds of sponsorships. Not only does she get paid in cash, but we get a lot of free stuff, too. We’ve received free rugs, free lights, and free carpet cleaners. She only promotes things she loves though, so this strategy works really well for her.
I’d say an interesting thought to add would be an idea suggested by Mark Cuban a while back on his blog. It was basically the idea that you’re not necessarily saving money so that you can invest slowly and retire comfortably, but that you were saving every possible penny, at every moment, so that when an actual fantastic opportunity came around you’d have money to invest.
Being rich means something different to every individual. Some people are happy with a decent-sized home and a moderate-income job, while others want to be millionaires and billionaires. Regardless of where you feel you fall on the spectrum, these steps can help you achieve the level of wealth you want. Before you get started, though, make sure to sort out your current finances so your bank account is ready to expand.
[JARED DIAMOND:] In Guns, Germs, and Steel I asked why history has unfolded differently over the last 13,000 years in Eurasia, in the Americas, in sub-Saharan Africa, and in Aboriginal Australia, with the result that within the last 500 years Europeans were the ones who conquered Native Americans and Aboriginal Australians and sub-Saharan Africans, rather than vice versa.
Rose and others looking for employment this summer: Retry the babysitting idea. Summer is a good time to babysit. Maybe volunteer a few times first and then use those families as references. Tell everyone you know that you are available to babysit. Use email, Facebook, fliers, word of mouth. Also try offering a set time every week, like Tuesday evenings form 5-9 pm in your home. Parents know they can drop off their children without calling ahead. They really appreciate that. It takes time and persistence to get the word out, butit can be done!

After an extremely intriguing conversation with Clothier, I began to better understand the concept of arbitrage and how anyone can use it to succeed in any industry. The difficulty here is first being able to identify opportunities for arbitrage, and later being able to fully leverage those on a larger scale. But once you find what works, expanding and scaling becomes almost instinctive and native rather than some grand hurdle.

Or again, what about the contrast between Microsoft and IBM? Again, since my book was published, I've acquired friends at Microsoft, and I've learned about Microsoft's organization, which is quite distinctive. Microsoft has lots of units, with free communication between units, and each of those units may have five to ten people working in them, but the units are not micro-managed, they are allowed a great deal of freedom in pursuing their own ideas. That unusual organization at Microsoft, broken up in to a lot of semi-independent units competing within the same company, contrasts with the organization at IBM, which until four years ago had much more insulated groups. A month ago, when I was talking in the industrial belt of North Carolina, the Raleigh-Durham area industrial belt, I met someone who is on the board of directors of IBM, and that person told me, Jared, what you say about IBM was quite true until four years ago: IBM did have this secretive organization which resulted in IBM's loss of competitive ability, but then IBM acquired a new CEO who changed things drastically, and IBM now has a more Microsoft-like organization, and you can see it, I'm told, in the improvement in IBM's innovativeness.

Jared Diamond was in New York several weeks ago and we had an early dinner across the street from the Museum of Natural History where he was scheduled to speak later in the evening. Jared first visited the Museum in 1963, when he was 25 years old, preparing to go to New Guinea on his first expedition to study New Guinea birds. Subsequently he analyzed his bird collections in the museum where he is on the staff of the Museum's Department of Ornithology in addition to his position at UCLA.

The competition is tough to get into these, so don’t rely on them as your only path forward.
If you don’t already have a job, you can try your luck with a day labor agency in your area such as Labor Works or People Ready. Generally, these jobs are of the low-skill, low-pay variety — construction helper, mover, retail or warehouse work. Arrive early in the morning, and if you’re chosen for a job, you’ll work that same day and receive payment at the end of your shift.
