When I walk around, I have many questions in my head. But I never stop to do something about it. If the question is important enough, it will stick and I'll do something about once I get back.

This is the modern curse: I know I can get an answer to nearly every question, and I can get it quickly, just taking my phone out of my pocket and dictating it, it takes zero effort. I feel it's worth to restrain oneself and just enjoy the walk. It just feels better.
