Yep. That topic.
In order to write and do it successfully, there are a few rules that must be followed. Learn your grammar, learn your punctuation, try not to write in the rock's point of view unless the story really -cannot- go on without input from said rock.
Other than that, the main thing you need to do is write. Continue to write. Write a lot, throw it away and write more to replace it. Write it better. Write it faster. Just keep writing.
As I've said elsewhere before, if you really don't like it or rejection and critique get you so down that you can't pick yourself up again, you're allowed to quit. This is not an until death do we part kind of thing for everyone. As someone else said, if someone can convince you not to write, let them. It may have been about screen writing. It may have been writing advice in general. I honestly don't remember and I'm paraphrasing.
Point is, everyone has ups and downs. Everyone has good times and bad times and everyone has to decide, from day to day and year to year, whether or not they're going to get up from one more tumble into the crap, wipe it off, and go back to the typewriter or keyboard or spiral notebook.
Just remember that when someone is dispensing wisdom or advice and you feel like the angels are singing. We've all been there. You'll be there too.
And the world will keep turning.
(No serial chapter today. Sorry! P'raps I'll update And The Skies Fell twice next week. Or later this week. We shall see.)
