GTD is NOT for everyone.<p>A productivity system that doesn&#x27;t make you feel good about your daily life is not be sustainable in the long run.  It doesn&#x27;t matter how effective it is, that&#x27;s not a life you want to be living.<p>What makes you feel better about your daily life will depend on your temperament.  The author of this blog post found that GTD resulted in his feeling like he had a never-ending river of stress ahead of him.  GTD failed for him.<p>Another example where GTD fails is for anyone who is doing sustained creative work.  As Paul Graham describes in <a href="http:&#x2F;&#x2F;www.paulgraham.com&#x2F;makersschedule.html" rel="nofollow">http:&#x2F;&#x2F;www.paulgraham.com&#x2F;makersschedule.html</a>, it is very important for those people to have large blocks of time set aside for focused work.  GTD&#x27;s focus on breaking things into simple tasks whose execution is routine is the antithesis of how work needs to be organized for a maker.<p>That said, GTD is life-changing for many people.  If it works for you, by all means do it.  But don&#x27;t make the mistake of trying to convert everyone else to it.  It isn&#x27;t always right.
