Could spend hours talking about ADHD which in this case is about how it creates executive dysfunction. A better term would be to call it Intention Deficit Disorder.

From personal experience, I know what I should do and the benefits of doing it, but I can't seem to actually 'motivate' myself to do it. I think in this day of smart phones and other distractions, it's so much easier to say 'this other thing I rather do' and it's not a matter of 'will power' it's the brains dopamine system literally telling you that.

Of course existential thoughts of 'why bother now' would also lead to procrastination and demotivation to the point of only doing things last minute, which actually might be too late.

My opinion, find the root causes of why and see if you can personally resolve them, if not talk to a Dr.

Congratulations, you've discovered that number systems are all arbitrary!

However, even when things are arbitrary, we would want to design them to be intuitive.

So I'll stay over here with my metric units.

Another thing is that these number systems do eventually interact with each other and having outlandish conversation tables is annoying and needless.

So yes we have good reasons why some of them are the way they are. Kelvin is scientifically easy to use, intuitive and fits right in with complex physics equations while Fahrenheit or whatever reverse system you are proposing would not.

Generous in what way though. The article was a study, they didn't have to actually be generous, they just had to say they were going to be.

Narcissists know what the 'right' answer is and can tell you that but does not mean they will actually do that unless it serves them. Also there generosity can usually come with a catch (loyalty, expected paybacks) The generosity is more like an investment to them.
