Many people feel anxious before delivering a big presentation or competing in an important event. They experience quicker breathing, a faster heart rate, heightened arousal. If we interpret these feelings negatively, then we feel threatened and tense up. If we interpret these feelings positively, then we can respond with fluidity and grace. You can reframe “I am nervous” to “I am excited and I’m getting an adrenaline rush to help me concentrate.” These little mind-set shifts aren’t magic, but they can help change the feelings you associate with a particular habit or situation.
