I fell out of a tree once. I like to climb and survey the view and leaned on the wrong branch.Falling hurt a lot but that view gave me good reason to climb trees every chance I got.I fell off my bike too, many times before and after learning how to ride it. I have a big scar on my left arm that hurt so much I saw stars. The times I ride a bicycle I feel free.An ex inadvertently taught me how unhealthy it was to allow my life to be all about my relationship. It hurt a lot to break up with him but in doing so I found myself. Here is what I can tell you with certainty: anything worthwhile will make you suffer."Potential pain" is not sound criteria for whether or not to try something. Because, you might risk missing out on everything.
