There's always rejection in any business.
What I do is overtime I build a portfolio of different businesses or affiliate programs.
So even if I am rejected for this business, I will try to find out what do my prospects need and offer them alternative solutions.
If I can't solve it, I will direct them to other business owners in my team whom I think can help them.

This way, I build good rapport from those who are not interested in my business, at the same time help to expand the businesses of my other contacts.
So it's always a win-win.
