For me, it was learning English. Although I do make a few mistakes here and there, I’m mostly perfect on it.
The amount of resources you have access to dramatically increases when you know a universal language. I say dramatically because it made me realize how much my native language lacks when it comes to certain topics. The most obvious one to me was tech and computers. Everybody knows how to use Windows but there are very few resources about stuff beyond Windows. It’s actually sad. [insert sad face here]
A “friend” started a company and hired me. It was pretty fun for a year. Then it became pretty bad — real bad. I quit on the spot after a verbal abuse session where I demanded more respect and my “friend” / boss literally said “no.”
It’s been a little over a year since I quit. Lived in my car for some of it, otherwise took odd jobs here and there where I could rent a room temporarily.
I’m at the end of this insane journey — starting a new job in a couple months. It’s been rough but I still think it was the right decision. Curious to see myself in 6 months to a year.
Anyway, felt like this was somewhat similar to your case.
