Rejections are a part of life. There is no other way around them. You need to embrace that fact. What matters is how you face them and what you do after being rejected. To be able to stand up again with the same bright energy you had the first time you started even after being rejected a hundred times will set you apart from pretty much everyone else. That is what separates a successful person and an average one. It definitely is not easy but if you can do that with a lot of practise, you are set for life. Build yourself a thick skin. You never know when it might come in handy.
