Your time is more valuable than money-and you cannot purchase more time with money.-so you cannot get back time. With that said though I think each decision needs to be studied a bit-but not to much and then go from there,so it gives you a start on how to go about your day. I think as you get older -you care about time more, because your time on earth may be limited(unless you can find a time machine like Dr Who-haha)?
