The most crucial thing you can do is this: finish.
Neil Gaiman tells us in his MasterClass that writers should not get in the habit of abandoning projects completely. Will there be times that you will have to come back to the work? Yes. But, you must come back to the work.
Finish things (even if you think they are ‘bad’), so you can write other things. Better things even.
Go forth…and finish.
