I remember being asked, “What do you want to be when you grow up?”
Much later, I recall thinking, “That’s totally the wrong question; it puts the cart before the horse.” I came to see that the more crucial question is, “How do you want to live when you grow up?”
Now, I’m coming to see that there is an even more foundational question than that, and it is, “Who will you serve?” You’re going to serve somebody; choose well, and keep well in mind that even the most monumental of egotists has a Master.
The correct answer is, of course, "Why would I want to grow up?"
That's still the one I use.
Maybe the whole point is to let yourself flow to where the Creator wants you to be. Maybe, “How may I best serve?”
