It's really tough. I bet that a good % of failed early stage startups fail because the founders simply can't keep up with the rejection and negativity. The simple truth is you just have to keep trying, for years and years possibly, before something really hits. Try not to think of them as rejections. Re-frame it as "this person isn't the right user for us right now." That removes the emotional bent from it, and maybe will force you to ask the question of "who IS the right user for us right now, and who's the right user for us tomorrow?"
