Good post Colin, Envy is quite an annoying emotion to have. It's so obvious when it pops up that "no I shouldn't be thinking this". It can be used for motivation sometimes as well. I think the emotion I dislike the most is apathy. It's so powerless, and devoid of anything. I try to watch and notice my feelings and emotions. Gratitude is the key for sure to truly combat most negative emotions. I don't believe that negative emotions will ever truly never come back but, the amount and how I deal with them is what is truly important. The more work you do on yourself the more layers are uncovered.
