It's happened again. I have somehow shifted into my mope (aka procrastinate) phase. In this phase, I consider my next action extremely slowly and without much energy. It's like I'm stuck. I'm afraid that if I don't consider further, I might break the functionality of my code; without considering that every change is a break. I'm afraid that if I choose to read the wrong book next, I'll wind up wasting time -- but the moping is wasting more time than I want to think about.
Whenever I get this way, there is just one cure that will work.
Act.
As soon as you start moving forward, you stop being excessively introspective and instead are able to exploit the potential in each moment. I know it sounds excessively motivational, but the next time you feel stuck in the mud, take action. You can take direct action or start focusing on something else.
