Robert Holden said this quote

The meaning of life is not a search—it is a choice. Meaning is not found in things; meaning is what you make of things. The world means nothing by itself. You give it all the meaning it has. Thus, the meaning of life is a choice you make, not just once, but every waking hour of your day. 

Life is like art—it is all about interpretation. The moment anything happens to you, you interpret a meaning for it. The meaning you vote for then governs your perception, your thinking, your faith, your choices, your feelings, your behaviors, everything! Whenever you elect a new meaning, this changes everything.
