As a leader, parent, or friend - don't let someone's poor attitude and poor performance hinder your commitment to holding them to higher standards. You don't need to make the person 'wrong' for the way they're behaving, simply point out that the behavior is ineffective.
Hal ElrodRemember that nearly all extraordinary accomplishments began by overcoming a series of challenges that discourage and tempt us to quit, before we succeed. Those that maintain faith, stay committed, follow through and keep moving forward are the few that achieve everything they want in life. Be one of the few.
