Ego is the enemy of team

If you want to get better and perform at a higher level the chances are that you will need to work with other people who are just as skilled and high-performing as you, if not more so. 

We need to shift our mindset from comparing ourselves with the others, to embracing what they bring. When we stop needing to be better than potential collaborators then great things can happen.

We all know of teams in work or sport that ended up being less than the sum of their parts because ego got in the way.
