Brad Paisley has a song titled the above. It's about a letter he wrote to his seventeen year old self.
I thought about that a little. If I could write a letter to seventeen year old me, I would say:
Take Spanish, not French.
Listen to your friends: don't get in the car with Mike.
Let some friendships die, pay better attention to others.
Finish Senior Year instead of going to work. (I did Work Release instead of classes)
Go to College in the Fall.
Don't kidnap your sister and make her fail Spanish.
Tell Dennis you're sorry & he was right.
Just take the damn Literature class already.
Try out for Show Choir...stop being so shy.
Slow down. Literally and figuratively
