I've been thinking about getting into some writing...

Start anywhere and rewrite and revise and add to as needed...

[big]Just Start![/big]

Don't think about doing it. Just do it. Only you can help yourself start it off, no one else can. Relax, take your time and start it off with what you feel is best suited for the story in your head. I'm sure it'll turn out fine. Good luck ! :)

I agree. Just write!
Plenty of time to edit; rewrite; add to, later.
Just get it out of your system and see how that feels.

Go for it! I love writing. It's so relaxing for me. And, if you need/want an editor before you post, I'm happy to be that for you. ☺

Just splatter out all the udeas first; you can shape it later and add fancy features like semicolons.
