Wearing all the hats sure, but more than that it's the craft itself that can be mentally exhausting and I'm not sure why. It requires a lot of presence. A lot concentration and I always work with this small fear of doing a mistake and ruining everything. That alone has a small weight to it. Learning new things is also mentally taxing.

I feel like creation is mentally taxing in a unique way but I don't know if it's just me. But yeah doesn't help that I wear all the hats too.
