I love seeing writers making peace with rejection. I think one of the best things you can do early in your career is to go out and seek rejection. Literally, collect "no's," collect passes. They'll always hurt, sure, but the more used to them you are, the better you'll cope.

Desensitizing yourself to rejection is also about understanding just what each "no" or pass means. You want to be able to recognize the difference between "this isn't good enough" and "this isn't what we want." You're not always told which is which, so here's how I've handled it:

I like to make two assumptions simultaneously:

1) No piece of writing is ever done until you the author say it is, or them the buyer/employer say it is.

2) Every rejection is because it "wasn't for them."

#2 is not objectively true of course, but here's what this did for me...

Still talking early career, it built the mindset that "No pass is personal, and no rejection is a judgement, but that either way, my work isn't done, and my writing can still be improved."

Accept those things simultaneously. "Rejection means nothing but the work isn't done."

Then go out and collect "no's," while seeing them for what they really are: Net zero.

You have not lost anything with a no, and of course have not gained anything, as you would with a yes.

So if Yes = +1, and No = 0, what do you really have to lose? Go get those "no's."

To this day, I have absolutely no idea how many things I've been rejected from, or how many times I've been told no. I don't keep track.

But I remember every single yes. Those came with paychecks.

I say all this to say, accepting rejection as a normal occurrence here is a milestone on your path forward. I forget who said it, but there's a quote along the lines of, "If anyone can talk you out of being a writer, they were probably right."

Don't let them talk you out of it.

Also, all of my best scripts so far have been a result of spite-writing.
