The problem happens when something is your identity. That's why it is difficult to change someone's mind.
Consider someone who is praying to God all their life. And you come and tell it's a sham. Even if you provide proof - accepting that means they were wrong all their life.
This is too much too handle.
So most people resort to sticking with their random identities.
If you want to learn a lot, get a sense of startup, have great founders, bootstrapped company then startup is a good idea. Especially at the start of your career.
But if you are late in your career with family, responsibilities and health issues - then startup isn't the best place to work.
I hope - you decide weighing everything and enjoy the process.
Maybe if the Workspace has some integrations options, it would be nice.
