Treat life like a game. There are a lot of unknowns and you can't predict everything or have all the facts, but you still need a gameplan.
Unlike a game, you can't win or lose. But play like you can. Choose some rules and a scoring system. Then play. Try to win.
Make up new rules as you go. Change your strategy. But remember that you have a purpose and that purpose is to win.
Fight! Fight! Fight!
