"I don't know if it's the change in weather that's making things easier; I'm a solar-powered life form at heart. Or maybe it's the work I've been doing to straighten out the inside of my head. Or maybe it's just sunspots, or coincidence, or happenstance."

People are complicated, and feel things for more than a single reason.

"Either way, I'm not going to question it; I'm just going to do my best to enjoy it while it's here...."

Sounds like a wise plan to me.
