Negative thinking is required for success

I heard that always think positive for success.Yes ,this is true.But there is a question . How can you think positive if there is no negative thinking.Be sure, night comes after each day.If there are good people , there are bad people too.If there is god is evil too.

If you will not fear to failure in examination then how will you read to pass it .You think that how will you pass in examination ,so you study. There is fear of failure is negative thinking whose drives you at success .

Older said that failure is mother of success.Failure is negative thing whose drives you at door of success.Because it gives you chance to think that where did you do wrong.Why did you fail to achieve your goal.You start thinking on your negative points.In other words , it gives you chance to make you better and meet the success. When you met failure then a fear comes in your mind if you will not work on wrongs points you will failure again and that fear is negative thinking which makes you a successful person.

A shloka in Sankrit "अति सर्वर्त्र वर्जयेत" .That means Extremes(Ati) of everything/ anywhere(Sarvatra) are to be shunned (forbidden-varjayet) . Hence plz don't think always negative .It makes you depress.Convert your fear which produce by negative thinking in your strength to work on.....

All The Best
