I have made a description of depression:
Depression is when you're waiting not to do things.
Happiness is when you can't wait to do things.
A distinguished psychiatrist commented:
"I was impressed by your inspirational use of the metaphors...valuable insights."
A renowned psychologist thought:
"I certainly think that you capture one important component of depression -
It comes with a lot of inertia and 'waiting'.
And the expression 'can't wait' (to mean excited) is interesting in itself - happiness often comes with a desire to get on with the next thing."
Come and get some inspiration.
