“Life is too short to be little.” Many times we allow ourselves to be upset by small things we should despise and forget. Here we are on this earth, with only a few more decades 
to live, and we lose many irreplaceable hours brooding over grievances that, in a year's time, will be forgotten by us and by everybody. Let us devote our life to worth-while actions,  simple living and high thinking.
Small talk and mistakes do happen. Let them not take 
up your time! Most of us worry about what never happens. Break worry before it breaks you!
