@Alex – what you said in your comment above: “the single goal would include multiple tactics” is a key point that I find people tend to miss. It is a subtle point, because a variety of tactics that all serve the one goal is not the same as having too many goals, but it can look that way.

For example, in my case, I make music, I write, I develop entrepreneurial internet products, and I am working up a fourth project (that may or may not see the light of day), so this hardly seems like One Thing does it? And yet it is because it all serves my Definite Major Purpose.

Having said that I have recently decided that one of these (music) needs to take precedence over the others due to the pressures of time. Last year I had ample time to work on all fronts, this year, with a changed employment scenario (i.e. I had to get a day job) and a baby that turned into a demanding toddler, I have less time so I have to focus my rare and valuable spare time more keenly. *sigh*

Good stuff.
