Avoid purchases that are likely to depreciate rapidly. Spending $50,000 on a car is sometimes considered a waste because it's likely that it won't be worth half that much in five years, regardless of how much work you put into it. As soon as you drive a new car off the lot, it depreciates about 20%-25% in value and continues to do so each year you own it.  That makes buying a car a very important financial decision.
It may make you think again if that's your real goal - getting rich. Felix says that he can understand looking back why others chose different paths with raising a family, devoting themselves to a worthy cause or non-profit, because he himself really wonders if it was worth it...NOT! as it turns out, he's too used to his freedom and experiences of the finer things in life that money affords to change his fate now. He shares with you in the book what a real bummer or hassle that having money brings including a long list of needed advisers, financial advisers, tax advisers, supportive well wishers who seek hand-outs, charities, not to mention the minute details and fine print of the tax laws that you'll need to get extra very familiar with.

And the results were unfathomable, allowing him to generate millions of dollars, almost on demand, while also becoming one of the leading internet marketers in the world, building up a massive list.
Two thoughts come to mind. First, at 27 you have a whole life in front of you, so whatever you do will be right if it is directed correctly. Second, pick a goal and work towards it (e.g., pay off medical debt; or pay off condo mortgage). Always remember, as you succeed in any one of these, then you can broaden out into other investments opportunities (e.g., stocks, mutual funds, real estates, etc.). The choice and timing are yours to call. My basic point; however, is while you are young “focus” on a GOAL and go after the goal aggressively.
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.
