If you can't handle rejection, then building a startup is not for you. Imagine you are the guy someone is trying to peddle something onto you that you seem vaguely interested in and then imagine telling that guy "thanks but not now". This is what you'll hear/get a lot, so you must deal with that first. Secondly, you need to make sure that what you are building is out there and reaching the people who really need it. Social media is great to get things going, but the person you want to target is the one who goes to a search engine and types: I need XYZ to do something and your result should pop up somewhere there.
