People teach people with difficulty; events teach people easily, in just one lesson.

Looking back on these years of crypto investing, the tuition fees paid have been truly expensive. Many foolish decisions I made seem both laughable and terrifying in hindsight—for example, buying 25 BTC to get a rune that I wasn't optimistic about even before its launch, just because I felt the market sentiment was there.
All the simple truths learned through paying a lot of tuition fees, yet I seem unable to clearly explain them to anyone. Perhaps everyone has their own tuition to pay.
