How to Over Come Negative Thoughts in life?

There are two kinds of thoughts: Positive and Negative. Positive thoughts lead us to the correct and right path, where as the negative thoughts often poison our minds, and lead us to the wrong path, polluting our thinking process and destroying our inner peace as well. The negative thoughts of pride, envy, anger, selfishness, greed and infatuation ultimately pollute our minds, how ever the positive thoughts of kindness, humbleness, help, care, sharing, honesty, etc. help to gain peace of mind. No one on this earth can deny the fact that their minds are a home to negative thoughts and emotions, many a times when we are feeling low in our life or some times, when we achieve success repeatedly, then thoughts of pride, envy, jealousy, etc. are common to occur, how ever, these thoughts lead us no where but to the path, that ultimately destroys us.
