Negative can be the catalyst for change, that's good. It's the way you're feeling, that's neither good nor bad but the way it is. If you feel negative you're aware of how you feel, that's good. How you perceive it is up to you, so if it's good or bad it's the choice you've made. If it makes you feel bad, that's bad. If feeling bad makes you want to change it, that's good. If you're confused then drop the whole good and bad thing, it makes Life easier and it brings awareness. That's good.
