It's a strange self-realization when one realizes that the most valuable knowledge they have in 2025 is their LLM prompt engineering skills, that have been acquired in only the last two years of one's life:

LLM Tricks
LLM Hacks
LLM Shortcuts
LLM Cheat Codes
Daisy-chaining Multiple/Different LLMs etc.

Even stranger to realize that if all of that knowledge were to be published online in 2025, it would mostly go unnoticed :-O
