Greater responsibility means more pressure to get things done. Become interested in David Allen's philosophy. People describe his approach as 'bottom up', which appeals to me; I've always been (even when I didn't recognise it) a 'bottom up' sort of person. It's one of the axes in the Myers-Briggs personality indicator - Sensing would correspond with 'bottom up', while Intuition is more 'top down'.
So, I'm reading the book, and trying to put it into practice. And finding all sorts of interesting tools to help me. And trying to integrate these new ideas with the tools which I already have - Microsoft Outlook on my desktop PC, and iambic Agendus on my Palm. All the while having to actually get things done (split infinitive for emphasis).
