I no longer believe it is possible to control our emotions, nor do I believe it is necessary. I believe we are supposed to feel exactly what we feel when we feel it, and we are supposed to use those emotions as energy to fuel our creations, to fuel our desires, to fuel our progress through our lives.
You cannot hope to control your emotions using your thoughts, but you can hope to control your thoughts using your emotions. But how do you control your emotions without suppressing them? After all, our goal is to master our lives, not makes ourselves mentally unstable.
