People Who Achieve Success: Success
"What's the secret to success? It's no secret You need a winning attitude, honesty and integrity, and a burning desire to succeed." -- Dave Thomas
It doesn't matter what the work is -- cleaning windows, delivering mail, or designing rockets. We can find joy in any kind of work if we focus on the quality of our work. On the other hand, we're not likely to find joy in work that we do sloppily or ineptly.
We may not be excellent at everything we do, but we should always strive for excellence. And when we do, we may surprise ourselves at how much enjoyment we can take even in the most mundane tasks.
