Get Creative
Whenever you feel that negative thoughts are creeping up on you, the best bet would be to turn your imagination creative. Think of a wonderful situation, where everything is happening as you planned or as you want. See yourself becoming successful in your endeavors, being loved by your near and dear ones or even getting appreciated from all the quarters. This would go a long way in helping you overcome the pessimism.

Look Back Into The Past
Life is never the same. Rather, it is full of surprises, twists and turns! At times, you win even without trying and during others; you lose even when you make a lot of effort. The wins have to be taken seriously, while the losses are something from which you need to learn. The moment you feel your losses gaining over your mind, try to think of those situations where success kissed your feet. Remember the sense of accomplishments and vow to make them happen again.

Indulge In Meditation
In case you are thinking meditation is only for those who want to lead a spiritual life and stay away from the materialistic world, you are wrong. People meditate for different reasons - developing their concentration, feeling one with the god, having a control over their thoughts, and so on. It is the last purpose that you have to solve with meditation. It will help you remain in a balanced state of mind and keep you away from the negativity.

Consciously Block Out Negative Thoughts
If you want to stop being pessimistic and think about the brighter side of life, it is very important to become conscious of your drift towards negativity. As soon as you feel that negative thoughts are trying to creep into your mind, start telling yourself ‘I do not have to think negatively’, ‘I have to think about the positive things happening in my life’, ‘I will not let negative thoughts come into my mind and affect me in any way’, etc.

Make Yourself Feel Happy
One of the best ways to get over negativity is to make yourself feel happy, by indulging in activities that you enjoy or that make your laugh. For instance, you can rent the DVD of your favorite comic flick and laugh your heart out. If you are fond of comics, buy some from the nearest bookstore and start reading. If you have internet at home, log on to the sites that list jokes, funny quotes or even funny SMS and start smiling!
