Doc Holliday: What did you ever want?
Wyatt Earp: Just to live a normal life.
Doc Holliday: There’s no normal life, Wyatt, it’s just life. Get on with it.

— Tombstone

You have your dreams. You have your plans. You have your life. No-one guarantees that those three things will ever intersect. The mark of a true adult is how you deal with what happens when life diverges sharply from what you want. A very wise old man told me a long time ago that you can either live through what life throws at you, or you can die. Just about everything in life boils down to that.
