Regret is the other. HAHAHAHA! This is not a lament. I want to talk to those of you that are in high school right now. If you are older than that, disregard. You already know what I'm about to say.
My daughter is seven years old with her whole life ahead of her (a condition we all enjoy, actually). It is easy to look at someone so young and see possibilities that somehow didn't show themselves or that we missed when we were young. My wisdom, in advice form, is this:
Go to college when you are young. It doesn't matter that you don't know what you want to study, that you don't have the money, or other excuses. The truth is, college will never be cheaper than it is right now. Scholarships, grants and loans are available. If you want to go to college, don't let anything stand in your way. GO NOW. If you think it's hard now, wait until you are older, with kids, a job, a spouse, a house, pets, what else? Life is full of responsibilities, but make it a bit easier on yourself and don't put off college for tomorrow when you can go today. You won't regret it.
