Full of Heart

I saw an interview with a secular music band. They were spontaneously asked, "What would you suggest to someone young, who wants to be in a band someday?" A long answer ensued. I heard and remembered one sentence..."Start taking as many opportunities as you can, even if they are small, making sure you do your best and that every effort is full of heart."
I am still pondering their answer. This could be a mantra to live by.
It made me think of this verse:
And whatever you do, do it heartily, 
as to the Lord and not to men,
knowing that from the Lord 
you will receive the reward of the inheritance; 
for you serve the Lord Christ. Col 3:23 (NKJV)
Heartily is an adverb. It means genuinely, completely, sincerely and with all one's heart. Are all of our efforts "full of heart?"
