Rejection in business

I want to talk about rejection, in every of our daily activities we face what is call rejection. from our love ones, from friends and family.
Like wise in business. As a beginner, i can remember marketing my goods for the very first time and all that was coming was rejection from my closs friends and some family members around me, i want to quit but some keep on telling me never give up, believe in yours you can do it. And today i can stand and tell others to believe in themselves and never to give up you can do it.
Once rejection starts coming in never loss hope, why? Because once you give up, that dream in you will die completely. But once you keep on pushing you will get to on top.
