Don't sweat the small stuff in Love = Chiisai koto ni kuyokuyosuruna. aijiyo (Paperback Bunko)

The book offers many small tips, but I wonder how the author chose which to highlight as most impactful. Were there specific stories or research that guided these choices?

Some of the suggestions seem obvious, but in real life, letting go of minor annoyances can be tough. How have others managed to stay consistent with these habits?

It’s interesting that the book emphasizes simple actions over big gestures. I wonder what led to this focus—personal experience, research, or a specific moment?
