A few maxims that serve me well, which might or might not serve you well. include:

• Reward the behavior I want, ignore the behavior I don't want.

• Get enough sleep. It's amazing how much smarter and more pleasant other people become when I'm not tired.

• Attend to likely motives. In particular, if someone says something, consider what they intend to accomplish by doing so. If I'm not sure, then I don't actually yet understand what they said, regardless of the words they used.

• Attend to the next thing. That is, large projects and future goals and so forth just tend to distract or overwhelm me; to make progress, I need to know what the next action/decision is, and the one after that, and the one after that.

• As K&P put it: "When you make a decision, do something. Don't just go somewhere or make another decision."

Never sign a contract under time pressure. One day per page might be a usable heuristic.

Resist the urge to answer this email right now, especially if it's important. Treat emails as you would postal mail.

Before entering into an agreement with anyone, try to set up a small obstacle that they have to overcome in order to close on the agreement. (For instance: meet you outside of their office, or buy you coffee.) If they fail this dedication test, perhaps they don't really want this deal.

The Marine Corps has two maxims that I find useful in beating akrasia:

-If you can’t get out of it, get into it.

-False motivation is still motivation.

If you have to do something, you might as well find a way to make it fun (even if its a stupid way). Being ridiculously overenthusiastic about whatever it is you don't want to do is often enough to make the activity enjoyable. In the Marine Corps, this usually amounts to Marines yelling silly sounds at the top of their lungs or doing things as fast as they can or in a overly exaggerated manner, but I can attest to the fact that the maxims work well in the my rest of life too.

When you come to move, and a thing you're planning to move is still in a box since the last move, throw it out.

If you are keeping a thing 'because it might come in handy' and the occasion arises when it WOULD have been handy except you forget you have it, throw it out.

On smaller purchases I note that I have a danger zone of between £3 and £8 where it's easy to just spend money without discernible benefit (it's no coincidence that this equals about a coffee and a bun in Starbucks). So I have a rule that unless it's something I actually need Right Now, I make a maximum of one such purchase per non-working day.

One I find useful for interpersonal dealings, as well as a lot of other things is:

• If you don't like the effect, don't produce the cause.

Seems like a simple rule to follow, but I'd say at least half of the mistakes I make are due to when I neglect this rule.

• Just because I'm wrong, that doesn't mean you're right.

The truth might be somewhere completely different.

Related to your original maxim: If you want to buy something, always spend at least five minutes, by the clock, thinking about whether the you of three hours from now, three days from now, and three years from now will be glad of your purchase.

This is a maxim that I only just now formalized, but it's something that, in principle, I always try to do.

I'm anti-impulsive by default. In the face of new things to try or do or see, saying no is easy, saying yes is hard. I usually enjoy new experiences when I have them, and I crave them in general, but I have to steel myself to have them. I'm afraid of doing things wrong because they're new, I'm afraid of looking silly because I don't know what I'm doing, I'm afraid of doing things suboptimally, or paying too much, or spending too much time at something, and so on and so on. Reflectively, I endorse none of these fears to the degree I have them. And so:

• Awkward and fresh beats comfortable and stale.

I run this in my head, and get some distance from those little fears, and that often suffices to do awesome things.

Wise men store up knowledge, but the mouth of a fool invites ruin.

-Proverbs 10:14

My personal version would go something like this:

More Anki, less debating politics on Facebook.

Get the small serving size. I now have this as a reflex:

"Would you like a small, medium or large ?" "Small."

"Regular, large or jumbo ?" "Small." *

"Would you like to supersize that ?" "No."

"Would you like fries with that ?" "No."

Avoids being flustered by a waiter / waitress looking at you or a queue of hungry people. Avoids overeating regret or plates of of uneaten food. On the rare occasion I finish still hungry, I can usually get a doughnut or something.

(* you don't have to conform to stupid linguistic inflation games, they know what you mean)

Eat sleep and have sex before making any big decision. Getting into that emotional ground state is valuable.

Think of the solution, not of the problem.

-- Terry Goodkind, Wizard's First Rule

Having your thoughts run in a loop about why your situation is horrible won't make it better. If you lock yourself out of your hotel room in your underwear, standing around in the hallway worrying about it isn't going to make going to the front desk any less embarrassing. You need a room key; go figure out a way to get one!

More seriously, the things you don't want to do right now are probably the things that you should be doing. Works for me.

Quote from Tom West (guy in Soul of the New Machine): Not everything worth doing is worth doing well.

The courage mantra: Courage is being well calibrated with respect to risk; for small games you play often (ie social interaction), if your scariest actions aren't failing as hard as they succeed, you're not being courageous enough.

If you can't predict the outcome with the outside view, do it just to get the data. (Be sensible: don't if you suspect large negative payoffs)

Model people causally, not morally.

This works for romance/sex, too. Have a hard wall on how far you'll go, and only move it when you're alone and calm. When you're in the heat of the moment, keep in mind that you can move it when you're alone and calm. You can even intend to do so -- and if when the time comes, you still think so, there you go.

Having that pressure release helps actually stay within the bounds you set. Otherwise it requires a great dal more patience.

I think high level generalizations are found in aphorisms and teaching stories from all around the world. They can sometimes be shorthand for a whole story, for example I often remind myself not to eat my money referencing this story:

Mulla Nasrudin, as everyone knows, comes from a country where fruit is fruit and meat is meat, and curry is never eaten. One week he was plodding along a dusty Indian road, having newly descended from the high mountains of Kafiristan, when a great thirst overtook him. "Soon," he said to himself, "I must come acr...
