The nice thing about most sports like rugby, is that you have a scoreboard to show how you've done. In other things in life, you don't.  At least, not one you can see.

Writer Helen Hayes once said that her mother drew a distinction between achievement and success. Her mother advised her that “achievement” is the knowledge that you have studied and worked hard and done the best that is in you. “Success” is being praised by others, and that's nice too, but not as important or satisfying. 

Always aim for achievement and forget about success.

Achievement is helping a person find out what they need, then helping him find the best way to get it. I Thess.2:11.
