You know, I'd love to tell you, but this is the challenge. I don't know if any of these excite me -- not sure if it's burnout or just pressure or something else.
It's totally fine if they don't those are just examples. And "you decide" was the wrong term. Your curiosity itself takes the wheel, you're along for the ride really. Instead of bitcoin maybe your curiosity will choose sock design, cooking, or collecting leaves. Just know that eventually curiosity will come. And yeah, burnout is real, good stuff written about it.

Well, what does excite you?
Keep in mind that excite can be almost any strong emotion, including things like anger, fear, or frustration, not just "it would be really cool if..."
Motivation can come from anything that gets your juices flowing, from "I can't believe they're actually charging money for this shit" to "dammit, why won't my gizmo talk to my gadget" or "oh no, $PROBLEM affecting $MY_COMMUNITY is terrible, what can I do", etc.
