Why most of the people tend to think only negatively?

It is mainly to avoid possible disappointment of something. In someway they do prepare to failure. For example someone wrote some examination. He wrote it better but there is a chance that he may fail in it also. He feels fear he cannot face the disappointment of failure if he thinks only success all the time. So he imagines himself that he has got failure instead of success. He thinks in such a way he need not feel disappointment when the results comes. But he does not know because of universal law of attraction he is inviting failure by his constantly thinking like that.

So it is very important not to think negatively at all. If you think you cannot face the sudden disappointment by particularly thinking positively then at least don’t let thoughts relate to failure into your mind even you don’t like to imagine success. But the best way is to think about success and imagine success. Thoughts relating to success treble the chances of success. It is not possible to change negative thinking into positive thinking at once. It requires systematic practice and it sure worths the trouble.
