Just tacking on to this, I'd also be careful to attempt to quantify what we gained by an experience, just because of the limitations of our words or thoughts.

Just tacking on to this, I'd also be careful to attempt to quantify what we gained by an experience, just because of the limitations of our words or thoughts. Just because there is 'nothing learned' or something doesn't seem beneficial, does not mean it did not have benefits that often can't be labeled. Also there's no goal to life, just a reminder. There's no like progress bar you fill up to 100% and then you win. You don't have to stay 'productive'.
