The Problem Is Out There

 

If the problem is outside of yourself, then you cannot fix it.  You can blame the world for your problems and be miserable.

OR

You can choose to be happy by working on yourself, you have negligible control over the world but huge control over yourself.  Unless you're a model or a professional athlete, you probably can do more than you're currently doing to become healthy, fit and attractive.  You can also learn to accept reality--most of us will never have the talent to be a model or elite athlete, but we can be out in the world and enjoy ourselves.
