Forget the past or know the future?

Hi,


1. You can know everything that will happen in the future, but your life will be rife with terrible things.
2. You can forget everything in the past (basically long-term memory loss), but your life will be filled with good things.
In other words, know the future and suffer for it, or remain blissfully ignorant of your past and have a good life? Which would you choose and why?


Please help.

I didn't find the right solution from the Internet.
