Love Your Work
Doing a good job requires a great amount of energy. This energy comes from motivating ourselves and setting our hearts aflame.
The best way to motivate yourself is to love your work. If you put all your effort into your job and do it well, no matter what it is, you'll gain a great sense of achievement, confidence, and the will to pursue the next challenge. Repeating this process increases your fondness for your work. Then your job is no longer a burden, and you can accomplish wonderful results.
Only after reaching this state of mind can you accomplish truly outstanding work.
