I gave this a 4 star because it was a good tale of truth but it didn't say anything all that new or amazing. I liked the story because I could relate to the time period and to my own reactions to the experiences I personally had during that same time as I took my turn at becoming rich. It was accurate based on my experiences...every single thing he wrote. But the hardest part then becomes keeping it.
People are always looking to have their cars washed and detailed. You could be a mobile car washer and detailer without having a permanent location. Reach out to people you know or make some flyers and put it in your neighbors' mailboxes. If you want to get serious about it, prop up a one-page website or give out business cards. You can make money quickly doing this.
