My advice to you, if you should ever be in a hold up, is to line up with the cowards and save your bravery for an occasion when it may be of some benefit to you.
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.
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.
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.
