Yeah, I know how you feel… Not only have I tried a lot of different programs, but have exchanged e-mails with others who are trying to implement GTD as well. “Have you checked out this program”, “This looks like it might work”, etc…

So, I use Entourage. Period. It doesn’t do everything; no program will. But it lists tasks, gives me reminders, lets me link tasks with contacts, and lets me create projects (though I don’t use the project manager for anything other than naming projects).

I’ve got a couple of other programs that I use to organize “stuff”: Circus Ponies NoteBook, BBEdit, and Inspiration when I need to outline stuff and make a flow chart of next actions.

I’ve found I don’t need all the bells and whistles of contexts (partly because I work in one place), nor do I use the 43 folders. 99% of my work is digital, so I have very little paper.

I think it’s much better to find a tool that does most of what you need, then get to work. Maybe once in a while, after you’ve finished all those next actions, cleaned out your inbox, and reviewed the past few weeks, then can you start looking for better tools. But none of them will be superior to a pencil and paper anyway.
