Siła woli. Odkryjmy na nowo to, co w człowieku najpotężniejsze

The book references numerous experiments and studies—I'm curious how he chose which ones to highlight and how he interpreted their relevance.

Some strategies resonated with me, but I wonder if others have tried them and seen real changes in their self-control.

This framing really shaped the whole book, and I'm curious whether it was based on his personal experiences or specific research findings.
