Yes, we've said a lot this month about how to control your ego and not to let it in the way, but let's be real, it can be OK to have a bit of an ego / know your worth.
While, you should take other view points into consideration and think of your team, it's important for you to know what value you bring to the table, and advocate for yourself. This means asking your coach to be honest with you about your strengths and weaknesses and working to improve them so you can get that starting post you know you deserve. It means being confident enough in knowing that when the ball comes to you during the game, you will get it to where it needs to be. Having an ego also means encouraging your teammates to play at their best -- after all, basketball is a team sport.
Think of it in NBA terms.
Steph Curry knows he's one of the best players in the league. He knows his three-point shooting abilities are expectational, and that he adds value to his organization. Knowing these facts helps Curry - and others players on his caliber - play their best, and work hard to maintain their status as leaders.
Remember, having an ego doesn't mean you can't be kind or humble.
