One kind of restlessness comes from choosing the fear of change:
What should I do now that will result in the least resistance and immediate gratification?
Why can't I be generous while looking at examples of others?
There is another kind of restlessness which arises from choosing the fear of wasting an opportunity:
What skill to learn?
Whom to connect with?
Whom to teach?
Whom to give?
Tranquility comes from knowing you are doing the right thing.
