As a kid and teenager, I used to vehemently hate clichés and "folk wisdom" delivered to me by family and friends. It took me until adulthood to finally accept them and understand them for what they are. And what they are is tried and true heuristics, that apply more often than not to situations in which they're invoked.

The problem with those is that they're just pointers, handles to a set of complex reasoning and personal experiences - so you're unlikely to grok a given piece of folk wisdom unless you thought about it and already navigated a situation in which it would apply. So for a teenager or young adult, they sound trite. But for someone with a couple decades of life behind them, they're concise.

Now that applies to the kind of clichés you'd find in a dictionary. The kind you see in this article/comic strip? These are just pseudo-zen bullshit peddled by self-help industry scammers. They pretend to be actionable, but are completely empty. I wish people would stop with those - not on the grounds that unsolicited advice is somehow bad, but on the grounds that these particular pieces of advice are objectively useful only to sell books and training courses.
