Side hustle as a dad - realistic talk

Everyone talks about side hustles as if you have free time. I tried freelance writing for a few months thinking I'd make extra money. Reality: I'd work 8-6 at my main job, come home, be present (or try to be) until kids bedtime at 8, then work until 10-11pm.

Made maybe $4,000 over three months. Burned out by month 4. Wife was annoyed I was always on my laptop. Kid asked why I was ignoring him during weekend mornings when I should've been present.

Decided the tradeoff wasn't worth it. Going back to just my regular job and accepting our budget as-is. Anyone else tried this and failed?
