How do you handle rejection?

Rejection is one of the most painful challenges that people could ever experience in life. For we are flawed, consider this as inevitable. Since rejection is part of our journey, the question now is, up to what extent could we handle this.

I've been rejected for the nth time already. Instead of looking for what went wrong, I've just come up of trying to find ways on how to make myself better. With that, I'm giving myself benefit of a doubt, that it's not like this all the time. Sooner or later, I would be getting what I'm deserving for.
