Ego is there to "protect" you and your sensitive image of yourself. Ego is the image.
Having an image of yourself is bad already, since you have to know yourself and not just have an image.
When you see a hot woman your instincts immediately say: "Go and approach her stud!"
But then the ego steps in the way: "But what if you fail. It would hurt your image of yourself. You might seem as a loser!"
And the fact is, if you don't try you are already loser who gets nothing.
To become a DJ, it's good to see who you really are first. Dropping that image of yourself (aka ego) you'll get to the bottom where the only way is up. You have to accept who you are at start. 99% guys here are complete wussies at start. Accepting that, they'll easy the process to become something better.
Plus, you know people who have huge ego. The kind who clearly think they are the best and are not. Isn't people like that annoying? I think they are.
Why?
-Because they have an image that they are better than others. And they still only have that image, nothing more.
You've also seen those rare people who don't brag about themselves and are clearly cooler/better/smarter/more successful than other but people absolutely love them.
-Those people don't cheat on themselves having an image of them being great, they have just worked to be what they are and are down to earth about that since they haven't let ego control them.
