The hardest part of sales is the constant rejection. Regardless of hunter / farmer / new business development or door to door sales.
How you handle your self talk is often the difference between success and failure - but as Dustin says below - positive self talk isn't bluster - it's about being truthful and accepting the face in the mirror.
"Self-talk is defined as what you say about yourself to yourself, and what you allow others to say about you that you believe." Before this I thought being positive is what having positive self-talk was all about. But after my conversation with Spencer, I realised that my self-talk had nothing to do with being a positive person. It had everything to do with looking in the mirror and honestly saying what I think about myself.
