Louis Pasteur, the great scientist, said "chance favours the prepared mind", which is a posh way of saying 'do your homework', but it's an excellent piece of advice.
I counseled many returning missionaries. I interviewed 1,700 missionaries all over the world. My advice to them is that you should study and prepare for your life's work in a field that you enjoy.
It is easier to give directions than advice, and more agreeable to have the right to act, even in a limited sphere, than the privilege to talk at large.
Although this garrulity of advising is born with us, I confess that life is rather a subject of wonder, than of didactics. So muchfate, so much irresistible dictation from temperament and unknown inspiration enter into it, that we doubt we can say anything out of our own experience whereby to help each other.
My second piece of advice is to stay global. As the world continues to change and we become more connected to each other, globalization will bring both benefits and disruptions to our lives. But either way, it's here, and it's not going away.
