The "Promote what you love instead of bashing what you hate," images are rolling around twitter and facebook these days. While I agree, and I've seen first hand how powerful promoting something you love can be, both for you and the person; I think it's foolhardy to ignore what you hate entirely.
The story with the ostrich sticking it's head in the sand is a good one, bad things don't go away if you ignore it. The same for tryingto think only positive thoughts, you can't make bad things or depression go away by thinking it away. We aren't magnets and the world isn't fair and sometimes hard work doesn't pay off. Sometimes life sucks.
BUT I've learned that you can make things work for you if you spend some time and are honest with yourself on how you can take that bad situation and force it to work.
My matra will be "Promote what you love instead of bashing what you hate; but keep a mindful eye out for the bad stuff."
