I really connected with this too. It stirred up old memories of what I thought my life might be like when I was in my twenties. Once I found these videos and watched them the YouTube algorithm started sending me all kinds of them.
My life has turned out similarly to yours, most of it was doing my art (writing) in my spare time until recently. Life happened and survival took precedence. It's worked out okay, better than I could have imagined. I'm thinking a lot about Act 2 lately. There isn't much of a future in writing books anymore. Every time I think about it the idea that comes to mind is just traveling and vlogging about my experiences.
