Excellence=Doing what you do heartily!

“Whatever may be your task, work at it heartily(from the soul), as[something done] for the Lord and not for men, Knowing[with all certainty] that it is from the Lord [and not from men] that you will receive the inheritance which is your[real] reward. [The One Whom] you are actually serving[is] the Lord Christ,the Messiah) Colossians 3:23-24 (AMP)
