Victor E. Frankl said this quote

The greatest task for any person is to find meaning in his or her life. Frankl saw three possible sources for meaning: in work (doing something significant), in love (caring for another person), and in courage during difficult times. Suffering in and of itself is meaningless; we give our suffering meaning by the way in which we respond to it.

~ Victor E. Frankl

Don't aim at success-the more you aim at it and make it a target, the more you are going to miss it. For success, like happiness, cannot be pursued; it must ensue, and it only does so as the unintended side-effect of one's dedication to a cause greater than oneself or as the by-product of one's surrender to a person other than oneself.

~ Victor E. Frankl
