Found this while looking for something for another entry.
Yes, let us not give up especially if you really want to do whatever you are doing right now. If JK Rowling gave up with all the rejections she received from publishing companies, we would not have Harry Potter to change our lives.
Rejection, failure, frustration, disappointment and all bad vibes are always in this cruel world. It will never be gone. All we can do is live our lives without concerning ourselves with these words.
And all the time you use would be all worth it.
May all our dreams come true! *cheers!*
