It's all about money.

As for bad advice.... Hopefully I've forgotten and ignored most of it... Oh wait... "Bitcoin isn't going anywhere, ignore it" that counts as bad advice I took on board about ten years ago and now regret.

To reject my experience-based heuristics/instincts for probabilistic thinking.

Great way to squander your hard-won understanding of something in exchange of garden-variety midwittery.

Still trying to unlearn that lesson.

Worst advice: "Don't try to make a carreer out of your passion"

The only professional I knew of as a kid repeated that lie when I, age 12, asked him for advice.

It was a meme from the 80's business 'genius' backwards-thinkers that I thankfully recognized as severely retarded. It took me 30 years to find out where he got that idea.

I learned at that moment that adults, the more credentialed they were, the more lies they would believe and spread around.
