One piece of advice I can offer (as someone with a similar wide range of interests) is that you should sometimes treat life like a field trip. If you meet an expert in something, ask questions and show enthusiasm. Experts (usually) love talking about their favorite topic. I know a gearhead who restores old cars who doesn’t talk much. But if I ask about any car, he will put his beer down and talk about different cars until the sun comes up. Chefs love talking about food. Most people like telling people about their life’s work (as long as you aren’t the type of asshole who tries to tell a Ph D they’re wrong because someone on the internet said something else).

Also, people say life is short. It’s actually simultaneously too short and too long. You won’t have time to be a Ph D level expert in all your interests but you’ll (hopefully) have decades to learn about whatever floats your boat. Life can get in the way but if you find hobbies you like, it’s restorative. Work and family responsibilities exist, to be sure, and lots of people feel too drained for hobbies but doing something fun isn’t draining.
