Every parent, sooner or later, must teach their child how to apologise. This is never easy - especially when the parent themselves is not particularly fond of saying 'sorry'. But it is healthy to have this ability. And the world becomes a better place, the more the people who live in it are able to overcome their own fear of 'loss of face'. If there is something in your life now that you wish could be another way - or that you regret - climb down by all means. But don't back down from anything from that you should be standing up to.   
 The fact that so much in life is cyclical. You may as well ask 'why get out of bed when you are only going to be tired again soon?' Or 'why wash the dishes when they will only need cleaning once more?' Now, is there any point in doing a good deed today? Of course, there is. You know there is. So do it.
