When your schedule is ripped apart for the next 8-10 days.
When you are going to be facing the toughest battles alone, with a smile on your face.
When you have to be nice to the rudest ones, because your behaviour defines you, not them.
I have invariably concluded in life that fortuitous events in life are like chess pieces purposefully placed in your path. If you treat those like a game and play your next move with stoicism, no one can stop you from winning. If you toss the chess pieces apart calling the game unfair, guess who is the loser? And I am not talking about the game.
