How do people stay in public their entire life??

Been out of public and in industry for months now so I can have my own opinion on the matter now. But like... I genuinely can't wrap around my head how people stay in public forever? Even if you wanna make partner, partners work a shit ton of hours too so like... what's the point? Obviously industry jobs can be hit or miss but to stay in public forever feels crazy to me now. I used to be anxious and miserable all the time and always felt like I was on the clock but now that I'm industry, I feel so relaxed while also being busy throughout the day. I wish better for everyone that never gets out.
