4 Ways to Handle and Overcome Your Fear of Rejection

Always have a rejection-processing protocol in place. Debrief with personal and professional support people who can empathize and appreciate your experiences without passing judgment, criticizing or looking to give you immediate advice. 

Overcoming rejection actually occurs from accepting the emotions that come with it.

In many cases, rejections are blessings in disguise. Maybe you don't want those customers that rejected your product.

Refer and direct those customers to your competitors that fit their needs. They certainly would not forget the lengths you went to. Such service is rare.
