There are two different ways to interpret this question - positively or negatively.
When I think of the positive aspect, I immediately think of family. Nothing is more important to me than my family - especially my son. Every time he accomplishes something new, my heart leaps! Hearing good news always makes my heart leap as well. I love hearing about positive things from anyone!
As for the negative aspect, seeing a snake or a big, nasty spider makes my heart leap for sure! Hearing my son cry out in pain also make my heart jump into my throat. I think the worst feeling in the world might be the sound of my son's sobbing because I know something has really hurt or upset him.
I hope that my life is full of many more positive leaps than negative, and I hope that yours is as well!
What makes your heart leap?
