It Is the Best You Got
There once was a man who had a cancer of the throat. Afterwards, he discovered that his voice was raspy and if he talked too much at a time, he got hoarse and eventually couldn’t talk at all for awhile.
He went to the doctor. The doctor told him that this condition was permanent. He would always be like this. “Just don’t use your voice much,” the doctor said. “Rest it a lot.”
But much of the time, the man kept talking until he went hoarse.
When asked why, he replied, “voices are talking. If I don’t talk, what am I resting my voice for?”
Economic laws would tell you focus on developing your strengths. Your comparative advantage. And, indeed, that is often a good idea.
But in the long run, specializing is terrestrial. Improving your weaknesses can be just as valuable, and more satisfying. Everything you have is part of you and meant to be used.
