Cut and paste is so much easier to do on PC, as is keeping an accurate word count! I can remember doing these tasks manually and that way is tedious to say the least. Cutting and pasting material can strengthen your writing as no writer writes everything in the correct order all at once. Having to move material is inevitable.
Taking me out of “real life” as there are times I physically feel the need for that.
When my stories and characters come to life and seem almost as real as “real” people, I receive a great deal of satisfaction as if knowing I’m writing “properly”, I’m “doing it right” as such characters need to “catch on”. If I can’t convince myself, I’ll have a hard job selling the book to anyone else.
Knowing this is something I am doing. Nobody can write my stories in exactly the same way so even if someone had the same ideas as me, the way they’d write the works out would be different. While not meaning to be an egocentric, it is nice to know there is something I do that’s unique to me.
