“You may not control all the events that happen to you, but you can decide not to be reduced by them. Try to be a rainbow in someone’s cloud. Do not complain. Make every effort to change things you do not like. If you cannot make a change, change the way you have been thinking. You might find a new solution.
Never whine. Whining lets a brute know that a victim is in the neighborhood.
Be certain that you do not die without having done something wonderful for humanity.”
This quote exudes a certain degree of Stoicism, a school of philosophy which was founded in Athens by Zeno of Citium in the early 3rd century BC. Its core teaching is asking people to rely on themselves and their responses, to control what they can control, and embrace things that happen outside of their control.
