9) Be Willing to Take Criticism
This is a tough one. You may want to better your gameplay but are you ok with someone else saying that you did something wrong? If you are honest with yourself (see item number 2) then this will be much easier for you. If you already think you are the best then you are probably wrong. If someone suggests something, especially in an area that you find that you struggle in, give it a shot. It doesn’t mean that they are better than you. It simply means they probably had the same struggle and they found a way out of it.
