A lesson...

Dear son,

When you're older you may notice that sometimes things don't go your way, or people don't behave the way you'd like them to. It's a hard fact of life, and I hope you don't have to face it too often. But when you do, keep in mind that everything is only temporary, and don't dwell on things for long once they're in the past. When you make a mistake, try to learn from it so you won't repeat it, but never punish yourself for it. And lastly, don't beat yourself up over whatever feelings or thought or emotions you experience in life; they're beyond your control; but your actions are not, so don't waste too much energy regretting mistakes or feeling sorry for yourself.

Love,
Dad
