I found this quote recently and found it quite interesting and apt. To consider both generally in life but also specifically at our particular failings.
Namely myself, as an avid over-thinker, I always consider perhaps way too many potential avenues to any given past, current or future situation. I, however, can spend too much time dwelling and not enough time acting on these thoughts.
For example when it comes to writing. I think as writer’s we are very critical of our work which can then cause detriment to the work in the long run. Take rejection, take failure, but do not dwell in it. All we can do is learn from it and much forward.
