People are not interested in your product or your business; they are interested in solving their own problems.
My life is on loan, like money borrowed from a bank. God is the lender, and He retains the right to call in the loan any time. Though I am responsible for taking care of it, I do not own this life; it is borrowed. Why should I fear its loss or the loss of anything else in this world when I must surrender it all anyway?
Ultimately though, we are not responsible for another's happiness. The unhappy person almost always suffers from self-inflicted pain.
