Years ago in a company I owned, there was a young man who worked for me who had tremendous potential. I believed in him so much that I personally invested in him and paid special attention to him. I thought his future with our company was worth the extra time. He never measured up to my expectations and we ended up having to part ways.
Every time I would meet with him to “encourage” him, he would say the same thing. “I’m doing the best I know how to do.” I have come to realize over the years that this response was actually his primary problem. He was doing the best he KNEW HOW to do.
