Go easy on yourself when you're not at your best. A lot of people are not at their best today. A lot of people never reach 110% velocity. Give thanks that you can get so high on life, and chill out when you fall below the uber-winning beast mode that makes you feel so excited.
Some of my depression is sadness at the massive amounts of my kid's lives I'm missing. That's real and that's going to make me sad. I don't have to dwell on it, but when it comes up I feel it, acknowledge it and thank my heart for feeling so strongly.
