A few years back I decided to borrow Stanley Tam’s idea and let God own my business by making him a senior partner of my music career and accordingly I am donating (no less than) 51% of my music earnings to charity/arts etc....  Stanley has a wonderful story (far more interesting than mine!) and he wrote about it here: God Owns My Business

“Thus, when you give to the needy, sound no trumpet before you, as the hypocrites do in the synagogues and in the streets, that they may be praised by others. Truly, I say to you, they have received their reward.  But when you give to the needy, do not let your left hand know what your right hand is doing, so that your giving may be in secret. And your Father who sees in secret will reward you."  Matthew 6: 2-4
