A little time invested in explaining something thoroughly can save hours later by preventing misunderstanding and fuzzy instructions. Don't bang your head against a brick wall. If a problem has you stymied, put it aside and come back to it when your mood and mind toward it have improved. Turn down certain demands on your time. It's flattering to be asked to serve on a committee or address a group, but these invitations are also cruel demands on your time and energy, neither of which is limitless.
Some people are think-skinned and overly sensitive.
Others are the victims of tactless, heavy-handed criticism from superiors. Whatever the reason, the individual who allows criticism to get under his skin is headed for a fall. He feels rebuffed and unappreciated, sulks, takes it out on his family and subordinates and soon finds himself as ineffective on the job as off. Assuming that the criticism was deserved and properly given, welcome it, be grateful for it, and determine to act on it. Remember that it is a valuable form of communication, for it is one key to better performance.
