Continuous refinement leads to excellence. Dedication is a must.

When you keep working at something on a continuous basis, you tend to achieve good quality of results. Dedication is most important as is diligence and discipline. Occasion hard work towards something is a hobby. If you have a passion, you have to keep at it on a regular basis.

I remember reading somewhere this as a kid:

Discipline + Diligence + Dogged Determination = Success !
