LOL - I think every providers number one hot issue is 'sleeping' ... cause IMO without a 'break 'to recharge ourselves those OTHER issues start to seem insurmountable even when they are indeed 'minor' things in reality ... I do not know about others but I could not do this for 10-12 hours a day without at LEAST a two hour quiet period the majority of days each week ... when I am breaking in a newbie and my quiet time routine is 'shortened' to less than that as a result I get burnt out quickly and my tolerance leash even for 'normal' gets really short before I reach the end of it... and I consider myself a generally very patient person specially with kids!
