your emotions, your brain, your body. They are all just meat. Much as lifting weight will make you stronger, studying will make you smarter, practicing recognizing your emotions and where they come from will help put you in charge of your feelings.

Think of a triangle. Each corner is think, feel or do. You can change the inputs on each corner and it'll affect the other corners. Having a feeling problem? Interrogate your thinking or actions around the feeling. Change them and see what happens to your feeling.
