I've had good success with the David Allen approach of Getting Things Done, in particular with the emphasis on context (e.g., "at the store", "at work", "at home"). In fact, I've had an empty inbox (to the amazement of past and present co-workers) for years despite growing amounts of email. And the context-dependent next-action approach I have found extremely effective. Everything else I take with a grain of salt (sorry 43 folder people).
On the other hand, the "5 year" vision that so many people seem to thrive on, I find myself avoiding that along with any "life goals". I'm just old enough to have achieved many of my goals and just young enough to be completely unsatisfied having achieved those goals. I have found happiness in the process but never the outcome.
For example, I enjoy traveling and I enjoy reading. I don't enjoy owning a bunch of books or owning keepsakes from my travels. It's not the book read (past tense), it's the book I'm reading that I enjoy. I don't enjoy owning nice things, I enjoying doing nice things. Happiness, for me, is in the process of life and not the outcome.
With that in mind, I realized that I'm operating under assumed contexts ("at work", "at home") that aim towards goal-oriented outcomes and not the process of living. I grew to have a different personality at work from home because I was separating those contexts (even though they often overlap). While this is understandable (and common) to separate work life from home life, ultimately I am one person and I'd rather not diverge my personalities into two competing creatures. I need better contexts to live within.
That being the case, I decided I will define and design my own contexts. I can focus my life on the process of living and design the very contexts to which I live within. I can let things blend and fall where they fall rather than forcing life into predefined areas. There is no reason to operate under the assumed contexts that the world and society expects of you.
The contexts to my designed life are quite simple: "creating" and "relaxing". I included a "meta" context so that I may continue to change the design, continuous improvement so-to-speak (I may never get it perfect but it'll get better). So far so good, I have blurred the boundaries of those conflicting areas. I don't have tasks "at work" or chores "at home"; I am instead living the "creating" and "relaxing" process of a designed life.
