I can't handle rejections, one is too many for me.
Rejections make us stronger, we must go on.
I will never give up, no matter how many rejection letters I receive.
After the fifth rejection, you should step back and take a look at your work, then brush it up.
The publishers must know something I don't, my writing sucks.
After a dozen rejections, it's time to throw in the towel and move on to something else.
