what books do you reccommend? to better myself?

I want to better myself. School has always came easy for me. I have a decent (starter) job thats great for my resume in building my career...but Im still pretty young and don't know what I want to do yet. I want to be well off, and to help others. I have thought about policing, teaching (highschool/college) or going into school seriously and getting a PHD in a psych area. But Ive been reading into ';flipping'; houses.my question is; if I can do the above (which takes years of studying, while going into debt) (or working for a pension like everyone else) why cant I build a successful realestate company? Any thoughts or advice would be awsome!
