You recognize this feeling. Being busy non stop.
I do not see my day divided by work and private. I go out of bed around 7 and to sleep around midnight. In between I do stuff. I am busy.
Being busy makes me happy. It is my quest. I feel it because it pulls my actions and efforts in a specific direction. I am striving for it every day. Persisting making things happen.
I am the happiest when there is a sudden breakthrough. But not only the point of breaktrhough, but the DO-ing to get there.
That is the right way of being busy for me. It is about rhythm. About not stopping. About maintaining my efforts. About enjoying.
