I had a similar goal when I was your age. I am now 27 and if things keep going like they are, I guess I'll reach the target even before I'm 30.

Some tips from my small experience so far.

(1) Don't take life to seriously. When I was in college, I started a simple business that kept very good pocket money flowing in - like your textbook business _might_. I spent every single cent that business brought in. I reckoned that after I graduated, my first couple paychecks will probably cover 3 years worth of pocket money savings. They did.

(2) Being a billionaire by 30 requires something extraordinary. Being a millionaire doesn't. The best way to do it is by working hard, saving money and being really good at something most companies will pay you for doing. You don't even need to be excellent - just really good, That, combined with a disciplined saving mentality will get you there quickly. It helps to live with your parents for as long as absolutely possible.

(3) When you start earning real money (after graduating - or maybe before if things go well) then save up a nice little bit. Invest in shares and so on, like you are doing now, but as soon as you can, buy a little house and start renting it out. Then pay it off and get another. And another. You'll hit that million mark pretty quickly that way.
