In order to be happy in life you need to do a simple thing. Use your ears as ventilation vents for selective audios.
Receive all the opinions, criticisms, suggestions, comments with one ear, and let them out through the other one without seconds delay. Like your head is a vacuum cleaner with one Suction and one Blower.  No negetive opinion  should remain inside you for more than 2 secs.

Try this method in office and home or wherever you usually confront negative opinions, sarcasm etc,  for 7 days for guaranteed results.  I KNOW I AM NOT OFFERING YOU SOMETHING NEW. THIS IS A KNOWN PRACTICE. BUT I AM REINTRODUCING IT FOR ACTUAL APPLICATION IN REAL LIFE.
