Many people's pain is not essentially because they are not good enough, but because they try to prove how excellent they are to people who don't need them. This is called "ineffective supply" in business and "self-motivation" in interpersonal relationships. It is important to understand a fundamental logic: value is defined by "demand," not by "ability." No matter how clever the dragon-slaying technique is, in a scenario where only chickens need to be killed, it can only be a dull knife; no matter how high the horsepower of a Ferrari is, during peak hours when traffic is jammed, it is equivalent to a pile of scrap metal. Do not force yourself to rebuild for an incompatible interface; that is a waste of personal computing power and a disturbance to others. A sign of maturity is to stop competing on the wrong track for "performance." It is always more important than effort.
