What counts as writing?

Here's something I've been mulling over recently - what activity counts as writing?

In the past week I've done the following (in no particular order):-

Edited
Written a synosis
Written a cover letter
Written a marketing strategy
Read a magazine article about writer-me and thought how best to use it
Blogged
Supported writing friends
Critiqued for writing friends
Worked on a budget for a writing workshop
Continued to plan with a friend for a writing workshop
Assembled and posted a submission packet
Mentally plotted a historical novel I will never write
Mentally planned when I will get on to my next WIP
Printed a 315 page MS (#@!@~&!! printer!)

All of those things are part and parcel of writer-me. They may not be essential to getting words on the page, but they are critical to my development as a writer - it's career development.

Do they count? I feel they're important.

But I suspect that sometimes only words on the page will do.
