Note to self: You simply have to keep learning, because you have not arrived.
Something inside you, called pride, wants to tell you that you know quite a bit. Don't let pride get in your way and prevent you from becoming what God really wants you to become and to hinder what He wants to do in your life.
People that desire the best for you will tell you information that will rub your pride. They do not worship at your throne and that will cause you discomfort. When they have loving, constructive instruction, you will question their motives, their right, their abilities, their upbringing, their manners, their hair color. A voice inside will attempt to get you to discount their instruction.
You will become so focussed on how troubled you have become, that you will run the danger of missing God's still small voice. When you are quick to answer in order to show your competency, you reopen the door for Satan to rear his ugly head.
Say things like: I am a self-made man. Sing songs like: I did it my way. Rely on no one. That'll show 'em.
Yeah, emulate what you see as a character flaw in others, don't look in the mirror too often. But the end will not be good. When the consequences of your own choices follow your every step, you will play the victim card - but no one, not even your own conscience, will believe it.
Your other option: Stay teachable. So, swallow your pride. Listen. Invite others to speak into your life. Be inspired. Take things to heart. Bite your tongue before you reject and say "no". You will be a better man. Remind yourself: You aim to please an audience of One; and you're not the One.
