what to do if you lost your job during corona

Just try to find a new one. I think if you are a great specialist you won't face any problems with that.

Not sure if this is intended for you? It's hard to say without knowing someones personal and financial situation but I would try to take some time to focus on myself and things that get me excited (doesn't have to be indie hacking).

I personally can't remember the last time I had a stretch of time longer than 2 weeks without having to worry about some sort of job, so I'd do my best to embrace the free time. See friends/family, write a book, play music or something, take some time to just do absolutely NOTHING.

There's way more to life than work but again, all of that comes down to being in the right position.
