If you're looking for perfection, look in the mirror. If you find it there, expect it elsewhere.
The last thing you do the best is what you have the most joy doing.
When one seeks assurance, there's none from those who respond, Now, don't you worry about a thing. If you weren't worried, you wouldn't have asked. If you are concerned, it's nice to know that those you query are, too. I'll take a worrier any day over a platitudinous reassurer.
When you don't understand, it's sometimes easier to look like you do.
Let your children go if you want to keep them.
Most of us are better when things go better.
