I have talked about a similar topic before. But if you missed it. I think that not knowing your future is way better than knowing. That gives you that anything can happen mental state. Otherwise if you know already that you will fail at something you may not even try it. Even though you might get some important lesson from that. What happens, happens.
And that losing a day in your life thing. I wish to live as long as possible. And try to be as healthy as possible. And I wouldn’t do anything that can shorten my life knowingly.
