New to this board and to the GTD process.

I've been thinking about organizing my Next Actions by sales opportunity (i.e., a specific sales opportunity w/ a current customer or new prospect) and was wondering what others are doing. My sense is that defining each sales opportunity as a project will simplify the process. Any thoughts?

Also, are salespeople using this process more inclined to use paper, digital or a combo of both for client/prospect Next Actions?

Thanks in advance for any ideas.
