What is luck?

I've read this article yesterday while flying to Bulgaria. It was talking about luck and humanity's quest of trying to define luck. I didn't know that some scientists do nothing else other than measuring luck in a society. Turns out that the majority of people consider themselves unlucky, especially in Germany. Funny that. And apparently Eli Lilly has developed a drug which makes people happier - well, it's just an anti-depressant!

To cut a long story short, here's the formula for becoming a lucky person:

1. Nurture your friendships
2. Write a diary for "luck": every evening, list 5 positive things that happened during your day
3. Just do things (stop playing the victim)

So here are my five positive things of the week:
1. My dad is still alive
2. I'm able to visit my best friend in Bulgaria
3. I'm healthy enough to wander the streets of Sofia for hours
4. I can't stop eating
5. I played Sqash today and won every game

What are your happy "things" these days?
