Over this weekend, I was wondering how my young kids, M & m, have a sense of wonder about the little things in life. Most kids are like that. They find joy in so many things: m is amazed when she realizes that touching a certain button makes a certain sound on her musical toy and claps every single time that it happens; M is so excited every single time she is in the swing in our neighborhood playground. We all had that sense of wonder at simple things when we were kids. When do we lose it? Would it not be great to have it all the time?
I have that sense of wonder with certain things like seeing the little ones becoming their own people. And I am catching myself these days to chill, take it easy, and retain that sense of wonder.

We lose the sense of wonder when we think too hard. We feel we need to control all emotions all the time. Maybe letting go a little always help there.
