I’ve been told that if you split your time between more than one thing you’ll only ever be average at any one of them. Whether sports, career, or whatever it is you are focusing the majority of your time on, if you spread your time and effort you will never be really good at any one thing.
Really?
I disagree. We can all be good at more than one thing, and the art of mastery has been disproven. Instead, I would propose that you will get good at whatever you spend the most time on. If you procrastinate, watch too much TV, laze about, then that is how you have chosen to spend your time and you will get good at doing that. Alternatively, if you spend your time learning something and practicing it, then over time you will get better and better at it. It’s common sense: whatever you feed will grow.
That doesn’t mean that you can only focus on one thing. There’s nothing stopping us from focusing on more than one thing, at different times. It may take longer but we can still become really good at more than one thing. It all comes down to time management and where you apply your focus.
