Use emotions to reflect on what makes you sad and happy, and why. Make sure you're not spending time on something that you think makes you happy but actually harms you. If someone or something makes you sad, evaluate what you can change and what you can't and make adjustments to better your life. Anger, go to the gym, go running, do yardwork, and let loose that adrenaline as you analyze the situation, then take a cool head and do what you need to do to resolve the issue.
