The first step that you need to make to the attainment of inner integrity, is to accept full responsibility for your life. Not look for the guilty and to meet the blows of fate with his head held high. Everything that happens, in fact, have done it, just sometimes it is hard to admit. No one can force us to do something against their will. Every choice is a decision independent. Once you realize this, life will become much easier.
Try to understand. Most often when communicating with people we only hear what we say, not paying attention to the meaning of these words. However, none of the emotion is not born in a vacuum. With anger and sarcasm often hides the fear of showing weakness. And mock disdain there's nothing like the fear of being rejected. Try to hear the person and sympathize. Power is the ability to admit and forgive the weakness of others.
Act according to conscience. When we begin to pretend and to seek justification for their actions, it only means that something goes wrong. For momentary success is very often have to pay too expensive. Don't treat people bad. Committing ugly deeds, we thereby sawing off the branch on which you sit. As a rule, all committed actions return to us like a boomerang.
Be yourself and don't nothing to regret. Sometimes, getting into a new group of people, trying to adjust in favor of the society breaks its foundations and principles. Of course, to be "stupid stubbornness" is also not what. But if you are neglecting yourself, you begin to do something or not to do just because so do all, that's another question. Be yourself calm and reasonable, and you will attract people with a similar Outlook, and those with whom you are not on the road, will disappear by themselves.
Most importantly live in the present. We can't change the past, the only reasonable tactic is to accept him as he is, and not to repeat past mistakes. Future has not yet arrived, so we can only influence at the present day.
