What's "risk" and why do you need to think about it?
It's true in many parts of life: no guts, no glory; no pain, no gain. And when it comes to investing, it's hard to get much reward without taking some investment risk.
But how much? Depending on the investments you choose, your account could take on a little bit of risk or a lot. Ultimately, what matters most is what you're comfortable with.
You should also keep in mind the difference between investing for college and investing for K–12 tuition expenses. College goals have a longer time horizon, so you may be able to take on more risk.
