I certainly spent many years in my early life chasing all over the globe for meaning and purpose. I'd feel like I'd found it, then it would fade away again.
I've come to see that the way my life shows up is actually my purpose.
If you want to know your purpose, look at the unfolding of your life, because that is your gift to the world. It may not look spectacular, but nobody else has the precise life that you do. It's a gift no one else can offer.
