Quotes from the same author

Trust only movement. Life happens at the level of events, not of words. Trust movement.
 Alfred Adler
We only regard those unions as real examples of love and real marriages in which a fixed and unalterable decision has been taken. If men or women contemplate an escape, they do not collect all their powers for the task. In none of the serious and important tasks of life do we arrange such a "getaway." We cannot love and be limited.

Courage is not an ability one either possess or lacks. Courage is the willingness to engage in a risk-taking behavior regardless of whether the consequences are unknown or possibly adverse. We are capable of courageous behavior provided we are willing to engage in it. Given that life offers few guarantees, all living requires risk-taking.
