Someone I'm too lazy to look up once said "Writers don't like to write, writers like to have written." And after careful consideration, I have something to say in response.
That crap is TRUE.
"Having written" something that's good, or even worthwhile, is great fun. You get to be proud of it, hear people talk about it, and enjoy the incredible satisfaction of completing something that you didn't just build, you crafted.
And if a piece turns out really, really well, sometimes it's even good enough to make you forget that actual writing is like pulling teeth. Like pulling your own teeth.
You agonize over wordings. You kick yourself for repetition mistakes. You rewrite sentences over and over, sometimes breaking your constructions with over editing-and all the while you wonder if you should just scrap it and start over.
Someone else once said, "Do something you love and you'll never work a day in your life." And after careful consideration, whoever said that is a LIAR. Work is always work. Loving what you do just means you get to feel good about it when it's done.*
*I could have phrased that better.
