You can't connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something - your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life.
Don't walk behind me; I may not lead. Don't walk in front of me; I may not follow. Just walk beside me and be my friend.
Everyone has highs and lows that they have to learn from, but every morning I start off with a good head on my shoulders, saying to myself, 'It's going to be a good day!' :)
