Why would you want to see your life in advance? Even if it could be seen, you would be disappointed. You would say you did not reach your full potential; you would say that you could have done some things better. You would say all of that and feel disappointed. You would give up on this life because you would feel that nothing could be remedied any more.
So why wouldn’t you instead immediately begin to make the most that is possible of your life? That way, when you look back in the end, you will be able to feel satisfaction at what was done, and you will understand that those things were in your life only to help you grow into the best version of yourself.
