Stress management, very important, I do 5-20 mins. counting 3-2-1 while taking a deep breath with each number every AM; actually took part in a biofeedback experiment which showed meditation (focused, controlled breathing) reduced several stress indicators.

also there is "4-7-8" breathing, which I've used in protests: breathe in count to 4; hold count to 7; breathe out count to 8...
