Human nature is such that our desires are formed through comparison with others.
And your happiness = Quality of your life minus envy.
On one hand, I am happy that I got into AI and boundless opportunities opened up before me, on the other hand, yesterday I came across a manual on testing the knowledge of an AI engineer-architect (I don't remember the exact job title), I opened it and realized that I can hardly answer anything there :) and I envy the specialists who understand all those expressions described in those tests.
