When you do something, if you fix your mind on the activity with some confidence, the quality of your state of mind is the activity itself. When you are concentrated on the quality of your being, you are prepared for the activity.
Shunryu SuzukiHappiness is sorrow; sorrow is happiness. There is happiness in difficulty; difficulty in happiness. Even though the ways we feel are different, they are not really different, in essence they are the same. This is the true understanding transmitted from Buddha to us.
