Positivity from the Base to the Roof

What we actually want is peace and this peace comes from mental satisfaction but the definition of mental satisfaction varies from man to man, breaking a good friendship is a reason of mental satisfaction of some people and rebuilding a broken up relationship is a reason of mental satisfaction of some people, so there are two types of people, one who are constructive and another one is destructive, the first one possesses positivity in them and the second one can be called as negative minded. Now the problem is that the people with positivity sometimes suffer from some mental conditions which are ischolar_main of negativity, such as depression, failure, frustration etc. Our life is so uncertain, even anybody don't know that whether she? he will be alive tomorrow or not, then why spend today with any type of negativity, if we do it we have to regret after leaving this world for not leaving my life with positivity, even we should not do anything negative because one day we will surely be conscious, may at the last period of life.
