Grabbed this off the internet. Really useful gauge for our emotions.
Look at where you are now and look at where you might be based on the image.
Do you like where you might be heading for? If you are on the right side, I doubt so. So change your emotions by controlling your thoughts. I have realised that by catching myself thinking of a negative thought, I can control and modify my current emotions.
Its midweek, so if you are stressed out by work or pissed off by someone, notice where you are and change it. After all, your emotions ultimately affects you. The environment or the other party will rarely be too affected by your internal state.
Where are you heading emotionally?
