Life Mottos?

In my last week of practicum, I wrote little notes to several of my kiddos.  Especially the ones I know struggle greatly with school, self-esteem, and just life in general.  What did I say in the notes? 3 phrases popped into my head (okay maybe 4)... my go to thoughts when anything gets hard!

Never say Never!
Nothing is impossible.
You can do anything you set your mind to...
Don't ask "why", ask "why not".
