To quote a slightly off beat song...

    How hard is it to decide to be in a good mood
    And then just be in a good mood?
    That's all I have to say because it's a straight up fact
    You control your emotions it's as simple as that

That's the core of the argument in basically all these things. I'm not saying it's true, but it is a perspective on life. :)
