Pride

Pride can be a lot like fire.
Useful in moderation.
Destructive when not kept under control.

It can help you stay warm in a cold night.
It can help you find your way in the dark.
It can help you cook your meal.

Or,

It can roar out of control.
It can burn down your home.
It can destroy other people, and yourself.

A little bit in the dark can help you find your way.
Too much at once, especially when in the dark, can blind you.
But in moderation. The right amount at the right place, at the right time...

It can be a great comfort.
It can be a great attribute.
It can help you keep yourself, when the world doesn't make sense.
It can help you to go on.

Pride, Ego, Anger and Fear, are not necessarily bad things. Not always. They just need to be kept in check. A little bit to help you prevail, to stay alive. But not so much as to destroy you.  
In the study of Systema, to learn this balance is important. To simply shun something which is ultimately part of yourself will only create inner conflict that will burden you and your training.
Rather than shunning these things and seeing parts of yourself as ugly, seek to understand them. Seek to understand yourself.
