When you do more than you're paid for eventually you'll be paid for more than you do.
When you stop planning and preparing . . . you stop winning.
What you do off the job plays a major role in how far you go on the job. How many good books, do you read each year? How often do you attend workshops? Who do you spend must of your time with?
Spirit is the most valuable asset, more than money and any other power.
A clear rejection is always better than a fake promise.
Check the records; there has never been an undisciplined person who was a champion. Regardless of the field of endeavor, you'll find this to be true.
