If you make a mistake, don’t spend precious time and energy trying to deny it or point the finger at someone else. Be a leader and own it, then spend your time and energy fixing the problem.

It's never better to make somebody poorer, even if they're rich.

Make a list of goals for every year, tick them off & reward yourself when you achieve each one. Will give much discipline in your life.
