Don't let anyone determine how you feel. All day, every day we are bombarded with peoples"opinions"of how we are and who we are at any given moment. They are not the ones responsible for how our day goes. We are. So If it's at work, at school or from your family, realize that someones assessment of you is not your reality. Know yourself well enough so that you're not affected when someone tries to pass judgement on you just to bring you down. Instead, diffuse them by simply showing that you know yourself and that you're not affected by their negativity.
