Difficult to say but I would come up with 3 main sources.
1/Surround yourself with people from whom you get energy, and say goodbye to those that suck energy. It is about giving and taking in a relation and if you are very honest with yourself some relations are one-way relations or better have become one way. Because people evolve, you evolve, it is not easy but you sometimes have to say goodbye.
2/Balance. As a dancer balance was very important, when you are on point and you are not in balance, no way you can dance on point with the desired technique. Afterwards when I got on a snowboard I had to work on that balance, as if you stay in balance on the board, you will not move.
So I figured that in life a lot is about balance, find your balance, female and male, ying and yang, stretch and release, run and slow time, active and reactive, listen and talk, grow and settle, give and take. Listen to your body
3/Get out of your comfort zone, be agile in the things you think and the things you do. It is good to have principles, but when they hold you back from growing you should be able to say goodbye to some of them and live with a new set of personal rules. But do not stretch the comfort zone to fast, too much, too far, you might get hurt.
I must say I realize a lot of these things still come from my life as a sportswoman. You go for the win, but you learn more when you lose.
