I hear you, I have found myself getting stuck on "what's the point/end goal of this, and is it worthwhile?" for some time now. Among other things, I am a sometime musician and writing music is difficult enough in itself, without thinking "there is so much music out there that it's unlikely that more than a few people will hear my music, so why bother?" Plenty of folks seem to just enjoy the journey and not think too hard about the destination, I'd love to be one of them.
