In Taoism and Zen Buddhism, life is often compared to a river. Rivers flow downstream on their way to the ocean, or their final destination. In the Liexi or Lieh-tzu there is a story of a man who comes upon a river, and fears to cross. As the man stands staring at the river he notices another man, swimming gracefully. The swimmer goes under with the current occasionally, and pops up for air occasionally. The man who wishes to cross does not understand how the man is so graceful, so when the swimmer comes up on the shore he asks him "What is your method of swimming?" to which the swimmer replies "I have no method of swimming, I simply go where the water takes me, and in doing so I always arrive exactly where I am going!".
I think this is an important story because we spend so much time fighting, stressing and wishing we could do things in our life. It is like swimming up stream or against the current. Maybe we can make a little headway against the current, but we would definitely end up exhausted quickly. It is much easier to go with the current, or, if anything, make our way to the riverbank to the side instead of trying to go upstream.
I find life much more enjoyable when I go with the flow, accept what is, how it is, and don't fight against it but go with it. Give it a try the next time you want to fight against life. Try letting go.
