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.
My philosophy is that not only are you responsible for your life, but doing the best at this moment puts you I the best place for the next moment.
In war as in life, it is often necessary when some cherished scheme has failed, to take up the best alternative open, and if so, it is folly not to work for it with all your might.
