People keep assuming I want to turn 500 bucks into a million. No, I am realistic. 500 into 525 is just fine. I guess I'll restate my point. I want to be a good example to my children. My parents couldn't be to me, so I think it's the best thing I can ever give them. My kids will respect and appreciate more the examples and life lessons than a car that will just might be a regret or a cool thing passed up.
This is the most important point of all - your kids will live their lives like you do. Acting in a responsible way will pay bigger dividends with your kids than any investment can. A certain level of income does not, in of itself, dictate what you should buy or own in terms of material possessions.
Good luck. Buy a Vanguard balanced mutual fund and forget about it. You'll find that the harder you work at investing may produce worse results. No matter how much time you put in, it is still a hobby to you. Its a lot simpler than you think to accumulate wealth - save a lot of money and don't lose any!
