That reminds me of an old proverb...Sounds about right to me. Keep 15 %of it and sell, and give the rest away. It's like something that owns you.
"Give a man a..." Wait — that's not it.
"If you owe a man $5,000; he owns you. However, if you owe $500,000,000 - You own him!"
I'm not sure how that even applies, but it reminds me of it.
