As you become comfortable with uncertainty, infinite possibilities open up in your life. It means fear is no longer a dominant factor in what you do and no longer prevents you from taking action to initiate change.
Eckhart TolleOn all levels, evolution occurs in response to a crisis situation, not infrequently a life-threatening one, when the old structures, inner or outer, are breaking down or are not working anymore. On a personal level, this often means the experience of loss of one kind or another: the death of a loved one, the end of a close relationship, loss of possessions, your home, status, or a breakdown of the external structures of your life that provided a sense of security.
Eckhart TolleWhenever you are engaged in something and there is an outpouring of energy, you are in enthusiasm.
