I've been thinking of starting a blog or a Twitch stream, which I want to dedicate all net revenue towards EA charities. I love my day job; it's impactful (improving access to US healthcare) and pays very well such that I can donate while living a comfortable life. Thus, I don't need the extra money that may come from my hobbies.
However, I'm hesitant since both activities are going to take significant time investment with minimal ROI in the beginning. I feel like it'll be fun to start, but it'll become a grind when I realize I'm not raising much money for the time I'm putting in. What if that time is better spent elsewhere for practicing EA?
I thought about doing freelance / volunteer work with my skills, but I think that's too close to work for me such that I won't enjoy doing it - yet, it would be highly effective.
