Being a typical Pisces, I might have experienced mood shifts, but I don't remember any depression, or needing to do anything, or to have someone bring me out of being depressed.
The only things that haven't worked for me are when I've held back. There's no reason to sell an idea short. The only risk would be to not fulfill the dream.
I thinks it really interesting how they throw the world music samples in there. I often wonder what it would be like to do something like that, but use my lyrics and my kind of style.
