What is the meaning of a sound out look life?

Life is not something to be preached about, but something to be lived. When we live, there will be frictions which normally will tempt us to think that life altogether is not good. That is not a sound outlook on life. Had there been no friction and resistance in life, we would all have lived as if in a dream and would have done whatever we wished, without even thinking about what its consequences and effects would be on the other human beings living with us. Therefore viewing these frictions and resistances in life as something essentially good for the ongoing of life is a sound outlook of life. Here, a sound outlook of life means one healthy to be adopted, which would promote and encourage the progress of life in a way that the person leading that life would feel somewhat a satisfaction in his actions in life. Lust, greed and jealousy are what commonly renders one's outlook of life unsound. The ancient scholars in the Orient have perfectly advised how to close the path to lust. Attachment leads to interest, interest leads to love, love leads to passion, passion leads to lust and lust leads to ultimately hate. Therefore to escape from developing a life of lust and hate lead a life unattached.
