It takes a lifetime of dedication to master a skill. One cannot be Gordon Ramsey by working weekends at the local truck stop. It takes a little natural talent and a lot of training and honing of skills.
Jack of all trades and Master of One. Sounds good to me. Which one, however. Maybe I could be a master of martial arts like Tony Jaa. He knows a lot of styles and seems to be very good at the ones he uses in the movies. I already know the forms of Tai Chi so that is a start. Maybe a master chef who can recreate a recipe by tasting the dish. There are so many things I like doing that I am good at; to choose one would be to shut down the others. I think I would not like to set my focus so hard. I should choose mastering the American English language, but I think I like the one skill that I have already mastered.
Being a Jack of all trades and a master of none is not a bad thing. My dad is that way. I come to believe he can do anything. The one thing that he was a master at doing is deciding what works for him. That one skill I learned from him, a master, and it has served me well through the years. Having a little skill in a lot of things works for me. I don’t mind at all being a master of my own life.
