food, to pleasure quite generally."
This is not in itself a life hack, perhaps, but it is an underlying principle of all of them. Strengthen your imagination and thus the core of your appreciation for everything of the best that life offers.
Pleasure is not very hard to find. The contemplation of nature or the enjoyment of any of the arts is inherently pleasurable, as is the company of good friends, so it's a matter of deliberately cultivating these pleasures. You don't even have to avoid displeasure any more than normal, because a greater receptivity to everything will create a more balanced perspective.
There are scolds who complain that people are attracted to attractive people, or to food that tastes good. This is almost tautological, though. Adorno scolded that aesthetics should renounce hedone. A lot of people seem to think that depriving oneself makes one a better person, but it really doesn't. I know that certain things are zero sum. So if there is a pie, and I get more of it, then you get less. But basic enjoyment of life works in an opposite way. If you are happier it is easier for you to make other people happier as well.
If your meal tastes good, you are not doing anybody any favors by not enjoying it. One way to not enjoy it is to be so preoccupied with other things that you don't even really taste it.
