Also hundred times this when you have kids. Sleep is important. It is much easier to get angry when you are tired. I sometimes wonder what good is there in not going to sleep when you are tired. Sometimes I sleep after lunch for twenty minutes. Sometimes even full cycle - one hour and half, but this is rare. It makes a difference - you are more fresh and although it may seem like a loss of time, it actually pays back quickly as you are not struggling with tiredness during your whole afternoon.
