German - welcome - i pm'd you about the car flipping.
basically, what you're doing is perfect for now. listen to tapes in the car is good. get tapes on BUSINESS also. corporations and LLC's and the like and just basic good information on business terms, laws, etc.
as for investing itself - do you own your own home now?
a great way, i think, to start is to buy OWNER OCCUPANT. it's a LONG TERM type investment, but if you do it right, man the money can really build up. does it take longer? yes, but i work with two people (married) who do it and they move every 2.5 years. they got a little caught up in their last deal - live on long island and saw the appreciation fall out from under them...but they're NOT overextended on multiple projects/loans like some builders/flippers i know.
anyhow - heck you could buy the owner occupant for the long term - start a corp or LLC, manage it correctly (paperwork), then start "flipping" - only thing is RISK and how much you're willing to engage in it.
flipping cars is one thing - flipping houses is another - more liability, more issues to deal with in terms of FINANCING, etc.
sounds like you're on the right track though so far.
keep in touch!
