You should start with adopting the ideology of optimism. All human beings, as we know, are divided into optimists and pessimists. First around trying to look good features, and the second round only see the bad. It is clear that the optimists are usually in a good mood, while pessimists depressed and sad. Depression and apathy are not peculiar to the optimists, since they are easily able to overcome such conditions.
Despite the fact that good to be optimistic, such people are not so much. If you look to others, most of them in one way or another to be pessimistic. Certainly, the same can be said about you. Such a simple skill like to enjoy life, is gradually lost in people prone to pessimism. Learn its features? Then it's time to take matters into their own hands and prevent further immersed in pessimism.
To realize the fact that life should be happy, think about what it is you have one. It seems that life is long, but no one really does not know how much he meted out. How much time is left for you, and that you will spend this short period of eternity? The joy of feeling alive, from what you have a body, home, family, job, loved one, children, cup of coffee on the table, but whatever! The most important things for you to the most simple and unpretentious, but gives life taste - everyone around you is something positive thing for joy as it exists.
If something does not add up, the first thing I think of is that it will pass. That everything will work out and formed. It happens always: for adverse periods always follow a good and quiet time. Yes, life is not a simple thing, but it is so interesting. Most importantly, do not be afraid to believe in themselves. Do not get angry and do not worry. It is better to try to calm down and think about whether you can somehow solve the problem? If yes, then go ahead.
When something does not add up at work or at home, always remember that everything will work out. When a person is nervous or angry, he makes mistakes that could be avoided by staying in a calm state of mind. Even if you are rude, just think what this man. After all, he always speaks, surely he lives in the same voice that spoke to you. This man poisons life itself.
Confidence and peace of mind - it's like armor, they can avoid many problems. Wear a "mask" relaxing facial expressions do not raise your voice, be friendly, and you'll see how most of the problems will disappear.
