Getting better is not a choice. It is a responsibility. We have only recently seen how top athletes push themselves at the Olympics and the Paralympics. The quest for improvement is what defines them. They know no other way to live.
Now, most of us are not going to the next Olympics but we can surely learn from those who will be going. Showing up each day, sticking to your plan, working on overall development, and relentless practice.
The same lessons are happy at work as well. I am yet to meet a co-worker who got better only by dreaming about it. You have to get up and do what is to be done. It might be good enough but you tried and the next time will be better.
As they say in running, the last person crawling in a marathon is faster than the one still on the couch!
