Atul Gawande 2 : Want to get great at something? Get a coach

Atul Gawande at TED2017
Want to get great at something? Get a coach (transcript)
Summary
Get a coach. No, no, no. People probably think that they don't need to get a coach. However, the speaker tells us that for understanding our accurate reality,  instilling positive habits of thinking, breaking our actions down, and even in the medical fields, helping patients up again, we need a coach.
First, we don't recognize the issues if we’re standing in our ways, we can't know how to fix them, and then we can't stop improving that is wrong, if we didn’t get a coach. In fact, we couldn't do many things that we’ve learned mostly from textbooks but we didn't notice it and no one could tell us. Every day, bad habits are continuing but it's not us but also around us.
Thus we and our team need a coach. It's not just how good you are but it's how good you're going to be that really matters.
