Amen to this

My son's commentary on life:

I was tucking him in tonight and he's fidgety. He finally comes out with this gem:

"I just don't feel right with the way I'm living my life right now."

I tried to clarify and asked what he'd like to change, if he'd like to exercise more or eat healthier or be nicer to friends and family. He goes:

"It's like we're in the desert and there's nothing to learn about but sand."

Can you please tell me how I'm supposed to respond to that?
