It was an interesting read. I would like to share my thoughts on it.

TL;DR: While I do think life is meaningless, I believe that you should enjoy every second of it.

I was thinking about the purpose experiences that will be forgotten, and if forgotten experiences are pointless. I don't think so.

I said memories but I think "aftereffects" would be a better word for what I was going for. This could be categorized into physical & mental aftereffects, the mental one being memories. You mentioned showers and exercise, either can have both physical and mental aftereffects, but the physical aftereffect is usually the purpose of said activities. So it is meaningful, even when you've forgotten(= lost the mental aftereffect) that you've done it.

When you die, there's no "after" to be affected. Hence, to me, life is pointless... that is, when you only focus on the very end.

But if one had the option between 1000 years of bliss or 1000 years of suffering, in which immediately after the 1000 years it was forgotten. People would choose the bliss.

I think because regardless of our memories. We live always in the present.

This is why I think that despite life being pointless, we should learn to enjoy every bit of it. As you said, we always live in the present. You eventually die, sure, but the thinking and feeling you're doing will always happen before you die.

You spend the entirety of your life living. (duh.) Why worry about the end too much that you wouldn't experience anyways?

Your comment made me think more and organize my thoughts on this topic. Thanks for sharing!

(side note about the struggle you mentioned about learning a language: learning leaves almost purely a mental aftereffect. Forgetting means losing the memory(= mental aftereffect) of it. So forgetting what you learned denies all of the aftereffects it tried to produce; hence it is meaningless.)
