Much as immortality seems to be a popular goal around here, "I want to live a long time" and "I want to be immortal" are both abstract and distant goals, which complicates motivation. My brain (and I suspect other people's brains) responds better to goals that are more concrete and closer in time.
E.g.
"I want to improve my chances that the hot girl/guy that works in the next department over will say yes when I ask them out"
or
"I want to run that 5k next summer in less than 30 minutes"
are much more concrete and immediate goals, and therefore more likely to succeed as motivation.
Hmmm...I'm not sure this is good advice. Goals per se aren't usually great motivators. And I'd say sex is a better motivator than an abstract numerical achievement. And "Next summer" is not immediate.
"Cryonics has a 95% chance of failure, by my estimation; it would be downright /embarrassing/ to die on the day before real immortality is discovered. Thus, I want to improve my general health and longevity."
That thought has gotten me through three weeks of gradually increasing exercise and diet improvement (I'm eating an apple right now) - but my enthusiasm is starting to flag. So I'm looking for new thoughts that will help me keep going, and keep improving. A few possibilities that I've thought of:
Pride: "If I'm so smart, then I should be able to do /better/ than those other people who don't even know about Bayesian updates, let alone the existence of akrasia..."
Sloth: "If I stop now, it's going to be /so much/ harder and more painful to start up again, instead of just keeping on keeping on..."
Desire: "I already like hiking and camping - if I keep this up, I'll be able to carry enough weight to finally take that long trip I've occasionally considered..."
Curiosity: "I'm as geeky a nerd as you can find. I wonder how far I can hack my own body?"
Pride again: "I already keep a hiker's first-aid kit in my pocket, and make other preparations for events that happen rarely. How stupid do I have to be not to put at least that much effort into making my everyday life easier?"
Does anyone have any experience in such self-motivation? Does this set of mental tricks seem like a sufficiently viable approach? Are there any other approaches that seem worth a shot?
