How do you stay motivated as an entrepreneur when facing constant rejection?

A large part of my motivation is derived from wanting to support my wife and son. After that, I am highly motivated by happy customers when I am able to successfully fix an issue for them. To see the satisfaction when something that has needed to be done for years is finally fixed, is so rewarding. There are bad customers in the handyman business, but so many are grateful and appreciative! They keep me going!
