In Madrid lives Norma, a very special Brazilian lady. 
The Spanish call her ‘the rocking grandma’. She is over sixty and works in various places, organizing promotions, parties and concerts.
Once, at about four in the morning, when I was so tired I could barely stand. I asked Norma where she got all her energy from.

‘I have a magic calendar. If you like, I can show it to you.’

The following day, I went to her house. She picked up an old, much scribbled-upon calendar.
‘Right, today is the day when they discovered a vaccine against polio,’ she said. ‘We must celebrate that, because life is beautiful.’

On each day of the year, Norma had written down something good that had happened on that date. For her, life was always a reason to be happy.
