START INVESTING ASAP! OPEN AN IRA, 401K..WHATEVER. I started investing when I was 18 (with my job in the military), sure I was broke all the time pretty much from the age of 18 to 25...but i kept investing..and now at the age of 33..I have a VERY NICE chunk of change in my investment accounts. Its nice to know that no matter what..I will be able to live comfortably when I choose to retire. And if I don't make it to retirement...my family will receive that money to better their lives.
You know that one thing you thought you wanted to do when you were a little kid? Do it. Don't wait until you turn thirty before you realize that you do have the talent before you start heading in that direction. You might find out you really don't want to do it, but you'll never regret the experience.
