As someone who switched meds, didn't sleep much for about 14 days and discovered modular synths: I'm in this picture and I don't like it.

Disclaimer: let's face it, I actually love it. Like others in this thread, I can't even imagine how boring I'd feel not discovering a completely new interest / hobby / aspect of life all the time.

Hell, I know so many people my age who simply seem to stagnate and are simply not interested in anything any longer, and I feel "protected" from that. Life is fucking exciting, let me try all the things!

There are definitely layers to this though, I have core interests that are more aligned with my personality, and I feel that governs how invested I am into each particular hobby. That doesn't keep me from having wildly varying interests, though.
