One of the most useful advice I got (forgot the name and the link) is to never got further than two replies deep. Every time I broke that, in hindsight, it was dumb to do so.
replies(6):
The mind loves to invent time regret in hindsight: "I should have cleaned the house instead of watching TV", "I should have spent more time with my kids instead of spending so much time at my job", things like that. Is that what you mean?
I'm on the train right now, I probably spent five minutes phrasing this comment (and if it feels like five it was likely ten) meanwhile I had a book I was going to try and finish and instead I squandered the ride on Internet junk food.
So to answer your question: yes, but no.
