Question about the Getting Things Done System...

[TesTeq]

If you are really a forum hero, why not answering the question instead of nitpicking newbies post and making sarcastic comment?

What question? I can't see it in your initial post.

But fortunately it survived in my previous comment:

For the paper based gtder, do you guys really use a new sheet of A4 paper to write an action reminder?
Did it ever strike you as wasteful?

So let me answer your question.

In the GTD book David Allen never tells us to put action reminders on separate sheets of paper. That's why I was wondering if you really had read the book.

David Allen mentions separate sheets of paper in the context of a mind sweep. Here is a quote from the book:

I recommend that you write out each thought, each idea, each project or thing that has your attention, on a separate sheet of paper. You could make one long list on a pad, but given how you will later be processing each item individually, it's actually more effective to put everything on separate sheets. You will likely not keep these pieces of paper (unless you decide that low-tech is your best organizing method), but it'll be handy to have them as discrete items to deal with as you're processing.

To summarize: collect each idea on a separate sheet of paper (or 3x5 card or post-it note or using David Allen Notetaker Wallet), put it in your inbox and then process it. Then these sheets of paper can be thrown away or used as a project reference items.
