Once that becomes habitual, you may find the other Maxims on productivity to be relevant: http://www.maxims.us/topics/productivity/
What? Ok... I bring one from another context who IMO fits well here:
"The point of public relations slogans like “Support our troops” is that they don’t mean anything… That’s the whole point of good propaganda.
You want to create a slogan that nobody’s going to be against, and everybody’s going to be for.
Nobody knows what it means, because it doesn’t mean anything. Its crucial value is that it diverts your attention from a question that does mean something: Do you support our policy? That’s the one you’re not allowed to talk about." Noam Chomsky
But perhaps your argument hinges on the assumption that 'hire a psychotherapist' is advice that diverts the attention from a more important issue. If that's the case, I'd like to hear what you think this might be.
The Chomsky quote wasn't just about that psychotherapist maxim, it's that one that made me tilted.
These maxims sound to me like if the job is not done it's the worker who got a problem and need to change. I'm just trying to say that maybe it could be the nature of the work and how we see it.
For example I am one of those who have really a lot of never-ending-awesome-side-projects. I'm fine with it.
As soon as I realize that particular job is more fun 'not to be completed' but because it allows me to learn more, share with others, discover techniques and occasionally strange weird reasons (wage?)! The completion is just a social reward (and yeah maybe I often fear the 'what to do next' desert).
The path to completion is so much more valuable to me.
We need more maxims to realize all the small ignored ends on the ongoing projects. Sometimes an idea is cool because of one of those ends, which is already done, and it would be a shame (and a time loss) to force yourself to continue.
P.S: I don't preach a do-never-finish lifestyle, it needs personal balance.
