Know or listen to those who know.
After a storm comes a calm.
Either you run the day or the day runs you.
Do not weep do not wax indignant. Understand.
It's always too early to quit.
What you do today can improve all your tomorrows.
Expect problems and eat them for breakfast.
Wherever you are - be all there.
The wise does at once what the fool does at last.
If you think you can do it, you can.
My experiences have taught me a lot and I'm happy with my learnings, if not with what I went through to learn.
