Sometimes being overtly self-critical can paralyze us. The danger is that once we analyze our defects we tend to judge ourselves harshly and become resigned. We mentally decide that our faults are too numerous to correct and give up.
Instead of introspection and action, we become so hung up on our smallest faults that we lose the confidence to set the process of rectification in motion. This leads to pessimism and finally paralysis. We give up on our desire to change.
