I find myself to be a fundamentally 'enthusiastic' person -- I love to act, and hate to refrain. Which shows up in things like health; I'll exercise like a dog and eat like a pig, because run is an action, but moderation is a lack of action (don't eat)
I agree, too, with your last paragraph.
But aside from that, even if individuals we do not find good strategies for better managing our weaknesses.... can we find better strategies for collaborating with others with complementary strengths and weaknesses? Of the people replying to you and stating a side, it looks like roughly a 50/50 split.
Is it possible for strong-restraint people to lend restraint to weak-restraint people? Is it possible for strong-initiative people to lend initiative to weak-initiative people?
Takes a bow
I'm great at putting myself through punishing training, physical or mental over a short duration but very weak in resisting things over the long term. For example, I've done endurance events that involve sleep deprivation, done intense 80hr/week work weeks when starting a business and even swimming sprint workouts so hard that I puked. But I've struggled greatly to avoid things like eating that extra 1500 kcal of cheese while watching Netflix from midnight to 2am.
The result has been a very high variance in my success at various endeavors. In the past year or so, I've been coming to believe that improving my weaker "negative" willpower carries a much greater benefit at this point than further improving my "positive" willpower. It's almost like the blades of a pair of scissors. If one it sharp enough, it can cut things on its own, but it's far better to have both blades at least reasonably sharp.
I've been reading a lot of research lately and sadly, it looks like willpower is determined by how developed (determined by genetics) or active (determined by exertion of willpower) are the prefrontal cortex regions.
We can train ourselves to have more willpower by exercising these parts of the brain regularly, but not by much. We hit our personal limit pretty fast and the best we can do then is to limit the amount of decisions we make...
On the other hand, many people seem to have the opposite problem; they find it relatively easy to do things that are unpleasant, but difficult to restrain themselves from indulging in the things that they enjoy.
Of course, you can have a mix of both problems, and it might vary based on what makes the activity unpleasant or pleasant. If something is physically addictive, then someone with strong restraint might find an exception there. And if a task is stressful or painful rather than merely cumbersome or boring, someone with strong proactive willpower might still have difficulty with it.
But I think it's worth investigating because it seems plausible that these are entirely different problems conflated by language. And it seems likely that totally different strategies would be needed for managing them.
