Defining moments are defining because they change the trajectory of who you are to the person you can become.
Looking back at your defining moments: Would you have made different choices?
Perhaps life would not be as good as it is today.
Unfortunately, that is impossible to know.
But you can be sure of one thing:
Your life would be different if you chose another path.
Rarely, it seems, the line we draw from A to B is straight. It more like a 2 year old with a set of crayons. All over the place.
