re: Best life quote that helps you.

I don't have any life mantras, but two that actually do pop into my head sometimes -

"Do the work, Don" - It's from Mad Men when Don is whining about his predicament and another dude on the show who has faced some trials and ridicule over the years essentially tells him to get on with it and get himself out of his out bad circumstance.

"Never watch another man work." - I don't remember where I heard it, but it's a good practice.
