If I had to pick between that moment and a lifetime of moments I am not sure what I'd pick

Yes, that moment is guaranteed, but a lifetime of moments–lovely or not–is much more valuable than a lifetime of contemplation

I'm sure that that moment wasn't as valuable as it felt
Our lives are just alternations between living and dreaming and I am afraid that dreaming is much more productive

Because living always becomes dreaming and thus logically dreaming should become living but it does not and I'd rather live my dreams than dream my life

Except that none of the above can occur

I'm not sure what I'd pick.
