>>9380802 ways: fast way and slow way.
Slow way is to get a wage cuck job, make a financial plan, and work and save for 20 years. If you made and followed a solid plan, you can have $1 million by your 40s if you start early enough. This should be your base line if you're determined to become rich.
Fast(er) way. Go with number one, but add more income. This income can come from side businesses you work on at night/weekends, a second job, investment income, whatever. The point is, if you add even $5,000+ to your savings every year, you can reduce the number of years it will take you to hit your number. If you're really determined, I've seen some people work a 9-5, go home and work on an ebusiness, write ebooks, and do stuff like sell houses as a re agent on the weekends.
>inb4 only $1 millionThis is what I'm doing. I've been working for about 1.5 years and have $40k so far. My main goal is only $500k in my 30s though. I'm told once you get $100k, the compounding interest becomes really noticeable.
