Saving for the Future?

This is a broad question, but would anyone have some quality advice/life lessons for a high school student that has a job and consistent paycheck? I could think of things to spend the money on, but what would be the best route for me to take so I could benefit from it more as I graduate and move on with life, even if its not a lot of money now. If it helps I am a high school senior, and I am going to college the fall of next year. I make around $400 a month, and I know it is not a lot but I was just thinking to utilize it best while I can. Thanks!
