I think it's okay to spend your money on anything you want... as long as you earn the money BEFORE you spend it. When you start buying those fancy gadgets with money you don't have, you will set foot on a dangerous slippery slope. How can you ever become a milionair when you rob your future self and expect him to pay you for it (interest)? I don't think you'll want to go there.
Now, for your goals... if you really want your own business, you'll need some funds to set it up and keep it afloat until you start making a profit. You'll also need an "emergency stash" for when things go badly, both in business and your personal life.
You must ask yourself this: is your spending helping or hurting your goal? Right now, it is hurting, because every dollar you spend, can no longer be put towards your businessfunds. It is possible to have the business and the fancy cars, but a more logical approach would be to first get your business going, make money from it, and spend THAT money on the luxury items you want.
You don't have to feel guilty about wanting to enjoy some of the finer things in life. Just make sure thise finer things don't
become your life, and you should be fine.
