Let assume for a moment there is some type of afterlife, but it isn't an eternity of perfect peace and happiness, where all your desires are provided.

What do you think, is the most important thing to learn here on earth, while you are still alive, that might help you in the next life? If there is an afterlife, nearly anything could be waiting there.

For example, it might be important to learn to be self sufficent. There may not be someone or something there to take care of you.

It might be important to learn to be adaptable. Like above, you might have to learn how to do new things, in a strange new world.

Perhaps having a strong ego and sense of self is importance. What if you end up in a dream like state or something like astral projection. A strong sense of self will help you from simply just fading away into random thoughts.

There are many things that may or may not help. I am curious what things people think might be useful in the great unknown of the afterlife.
