You must be open for happiness and build it with time. If you are pessimistic with constant negative thoughts, there is no way you can feel happy, even with the really nice things in your life. Without gratitude, you'll always be complaining without recognizing how lucky you are in many ways. When you are sad, try to think about something good. Don't insist on thinking about your problems.

If you focus on what is good, your mood will change. Your disposition will be much better and in a while you'll start really feeling better. Your mind is transported to the places that you think of, so if you start thinking positively and remembering good moments of your life, you'll be transported to other places when you lived situations that you liked.

This is an exercise you should do, so that you learn how to feel fine and stop worrying about the same problems over and over again, even when you are full of problems. You should think about them until a certain point and try to solve them. Once you find a solution or a way to find it, you should stop worrying and think about something else so that you may keep your peace of mind.

Of course, this is not easy, but you have to initially have the open attitude of a person who understands that there is no point in obsessing with something and accept to think about something else. If you insist on considering the occupation with your problems important (even though you have already found the solution or the way to find it, or have simply understood that you cannot solve them...) this occupation will steal your peace of mind and you'll feel depressed.

You may not even be able to sleep. This is the problem with people who suffer from insomnia: they keep thinking about their problems. Everyone has problems, and many times they are serious.

Of course you need to think about your problems, trying to solve them at the soonest, but if you overdo it, in the end, you'll have another problem to face because of this manic obsession with your problems as if you could automatically solve them by thinking the same things over and over again. The ability to abandon a hypothesis that was already analyzed is basic for your psychological and physical health.

Usually, people who suffer from insomnia or are constantly pessimistic believe that their thoughts are unavoidable and that the reason they cannot rest and feel fine is the existence of their problems, not their attitude.

If they were right, nobody would ever sleep at night...

Problems, dangers, fears, everything that frightens you and every challenge you have in your way shall be part of your concern, but you shall not be blocked by them. I'm not talking about total indifference to your problems and an irresponsible attitude, like the attitude of people who sing and dance while they should be working to pay their bills or trying to correct their mistakes.

I'm talking about the insistence upon negativity and pessimism and in the adoption of a constant worrying attitude. I don't know if you ever noticed it, but some people have the nervous and worried attitude all the time. It characterizes them so much that they are not able to show joy and satisfaction even when they should be happy for some reason.

Of course, if you have very serious problems or if you are not self-confident, you need help in order to stop worrying at a certain point and relax. If this is your case, start writing down your dreams and learn what the wise unconscious teaches you.

You'll see that the way you feel and your actions will not depend upon the external world. You'll build your internal safe refuge, thanks to which you'll keep your peace of mind and will be always satisfied with yourself, no matter how many problems the outside world may bring you.
