One thing at the time, or confusion emerges.

It is said that in life you have two important moments, the one in which you are born, and the one in which you realize why you were born.

Anyway, once you come into the world, you have only one guarantee, which is that you will die. The problem is that most people are already dead before they turn 25, but they are buried after the age of 75. 50 years of zombification.

Thinking logically, life is just a short intermezzo in our long death, because we existed long before we came into the world and we will continue to exist long after we die of age, disease or other reasons. Apparently we come into the world screaming and yelling, so it is not very comfortable in the world compared to the place where we come from, and no one has yet returned after death to stay here because it would be miserable there.

In fact, all the cases of "near death experience" in which some almost died, had "out of body experiences" in which they left their own corpse in the hands of those from the Emergency Resuscitation and happily walked among the living waiting for them to leave joyfully this world, when the one from reanimation brought them back to their bodies, they were sad that they had not let them go in peace, and they lived the rest of their lives waiting to die once and for all.

As a result, we cling to this life, we drink, we eat, we make fortunes (by stepping on corpses), we cause a lot of suffering to others for our own good, and when we leave, we take nothing with us except our thoughts and what we have learned, invented, created in our minds, the rest... is chasing after the wind.

Conclusion: Memorize everything you catch, once you're dead you don't memorize anything anylonger, invent everything you can, once you're dead you don't come up with ideas anymore, learn many languages, once you're dead I don't think it'll help you at all, but the fact that you broadened your brain with them yes, that will turn usefull to you, and especially help everyone without ever asking for anything in return, their gratitude seems to be the only currency that will accompany you beyond.
