Sometimes I let negative comments upset me. Not to the point where my day is ruined, but I will feel some kind of sting from the remark for a moment.
People have been making negative remarks since the world began. Cain hated Abel and Julius Caesar was assassinated, George Washington had people who couldn’t stand him, and people probably said plenty of negative things about Helen Keller.
The people making negative comments will end up dead, and so will you. The world is a much bigger place than either you or me or that guy who is making nasty comments.
Instead of stressing, condition yourself to start looking at the world as a place where you’re connected to your past and building for the future. Those petty comments in the here and now will be forgotten by next week, but your work, if it’s worthy, will stand the test of time.
