Episode 19, Season 4 Chuck Versus the Muuurder
Director Bently talking to Chuck, "You know what your problem is? You want people to like you too much. A good leadership doesn't care about that."
In life, you can't have everyone to like you, and you can't be a good leader if you're affected by this. Just be confident and do what is right.
On the same line of thoughts, why not accept criticism positively with appreciation and allow yourself to improve. As this great article from Zenhabits mentions, most criticism is not an attack/insult on you as a person, but rather on your actions. It's up to you to be the better person, or react angrily and regret later.
