What happens if you let yourself succumb to a siren call?

There are activities or people or things in life that call to us, and we resist. We believe they are not good for us. But is that true? What happens if you succumb joyfully to that call? Mightn’t you come out the other side more easily than if you had resisted mightily and then succumbed?

Have there been siren calls in your life that you’ve resisted or succumbed to? What happened? What did you learn about yourself?
