You're aiming way to low. By the time you're 30 you may be married, might have a child, might like a home. If you drift into Silicon Valley proper, where I live, your $100,000 will not allow you to buy a house. What were once working class neighborhoods are now filled with $2.5 million dollar homes. (But the houses are the same.) Aim higher, or learn to love to commute.

Most importantly, enjoy what you do. No matter how much you make, if you hate going to work, it won't matter.
