so i've been combing through the GTD book the past month, and i have a question that doesn't seem to be answered in the book. i'm glad that i found this forum. from the anecdotes that he gives about his work with clients and even examples that he gives to make his point usually involve "grown-ups." and the things that they deal with. but i'm 24, just starting out in my career with a modest number of responsibilities, goals, and aspirations. i came across this whole world of GTD through my love for blogs; particularly 43folders. but not really because i had so many responsibilities and i was so overwhelmed that i needed desperate help.
so in a situation like mine, i was wondering if anyone can give me insight on how someone like me can use this effectively. ie: how many next actions/waiting for tasks one should have, how many projects, (Allen emphasizes that you should have at least fifty of them at any given point. Mine is about 20-30), how can i further implement this better as i start to gain more and more responsibilities and things going on in my life. in essence, how i can start implementing this great strategy even if i don't have kids to raise, business to start, bills to pay, investments to make, etc.
i'm not an executive by any means, but my goal is to become a productive one as i grow up using these methodologies. thanks in advance, and will be glad to clarify if need be.
