1. "Don't sweat the small stuff. And nothing's the big stuff." I don't know the occasion that led to those words being spoken to me, but it was a light bulb moment, giving my constantly tense and wound-up childhood self a chance to relax and not be in constant fight or flight mode.

2. "Mindfulness of Breathing" Practicing that meditation allows me to feel the ebb and flow of my thoughts and bring them to center. It's nice to treat my thoughts as a river to channel rather than an enemy to beat.

3. "IDIC" Infinite Diversity in Infinite Combinations. While that phrase and the corresponding symbol was a marketing gimmick for Star Trek by Gene Roddenberry himself, it's not a bad sentiment. For the show I love as well as the world around me. The world is an interesting place, with so much uniqueness. If you know where to look. And I want to see as much of it as I can!

Same question (Reworded somewhat.): What are some ideas you learned (and internalized) in your younger years that shaped your life for the better?
