All our future careers will be like the careers of elite sports people: If you play soccer at the top of the game, you understand that by the time you get to 33 years old, you move on. And if you haven’t prepared properly, you’ll be in trouble. (A well advised top player knows they must save money, and train for a new career which might be in coaching or as a TV presenter, or something else.) This is how it will be for everybody from now on, irrespective of what you do! Keep your mind flexible, be forecast, be innovative, make things happen, steem it, roll your sleeves.
