It can be time consuming for sure; paths diverge and split off again and before long one has spent three hours delving into one single aspect. Do that every day and yep, it eats into ones time. I enjoyed it though, and feel I have gotten a lot from it, personally.

Maybe you'll get to it at some point, I think a person needs to be in the right frame of mind to do so, that's when they get the best returns from it, the most enjoyment.
