First, pay off any debts, such as car loans, mortgage (doubt you have one as you're in high school), etc. If our money, one day, becomes worthless, at least you'll have your posessions paid off.
Since you're in high school, enjoy your youth. I didn't save anything when I was that young, and I have no regrets. Now that I'm older, I save some, but not as much as some would. I enjoy stimulating our economy. You could die tomorrow, and you can't take a huge savings account with you, but you can enjoy the things you buy today.
