Be kind whenever possible. It is always possible.
Always desire to learn something useful.
Know or listen to those who know.
Begin to be now what you will be hereafter.
Never complain and never explain.
If you're going through hell, keep going.
What you do today can improve all your tomorrows.
Go for it now. The future is promised to no one.
After a storm comes a calm.
The dog that trots about finds a bone.
I did make some not-so-great relationship decisions when I was a lot younger. I do know that not all high school boys are great and wonderful and Prince Charming, and there are a few that are going to treat you that way.
