nº 8 : ' Forgiveness '

Forgiveness means a long memory of all the times when we wouldn’t have got through life without someone cutting us some slack. It’s recognising that living with others isn’t possible without excusing errors. (AdB)

If you can forgive others, yourself and the world their imperfection, it's a lot easier to feel appreciation for what is nice, right, good or beautiful no matter how little it may be. That is the starting point for good attitude: Embrace all the good and the bad will affect you much less.
I say to my children (real computing miracles): put on your %-) glasses and find out how well everything and everyone scores.
