Dear Clarity members

Answer
Legge One with tears flowing in torrents and graning in sorrow.Good fortune.

Modify yor behaviour mood value system.

So don't be so miserable, depressed about life.
Look at the positve things in your life which are there.

Actually I am not depressed but am a bit of a glass half empty type.
Has anyone ideas how to stop being like this?
Or good books to try out?

Again thanks in advance any ideas would be well recieved.
