/biz/ - Business & Finance

I'm a 19 year old web developer and I'll be making 70k annually starting December.

My goal is to learn how to turn this money into more money before I have any real responsibilities and to have enough saved by 21 so that I can support myself while pursuing entrepreneurial ventures.

My only expense is my phone bill, and I'll probably finance a 10-15k car for my 20th birthday (March 29th)

I started at 44k in May and I get raped on taxes (2k biweekly check comes down to 1500~). I'd really like for my income to start generating income, but I dropped out in the 9th grade and I only have very basic knowledge on micro-economics.. I grew up in the inner city and I never seen money like that before (1k is laughable now that I see how fast it burns).

/biz/, what is this money thing and how do I manage it??
