The most effective worker is generally the busiest.
Successful people are busy people. They despise idleness and constantly search for new challenges and better ways to do things.
When others discover that you are thoughtful, helpful, enthusiastic worker, you will soon have more business you can manage, and you will greatly increase the number of people who have a stake in your success.
The most mundane tasks become much more bearable when you compete with yourself to improve at doing them.
When you find faster and better ways to do your job, you also free up time that can be spent in more creative pursuits.
