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.
Here's my advice to you: don't marry until you can tell yourself that you've done all you could, and until you've stopped loving the women you've chosen, until you see her clearly, otherwise you'll be cruelly and irremediably mistaken. Marry when you're old and good for nothing...Otherwise all that's good and lofty in you will be lost.
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.
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.
