Increased heart rate, rapid breathing, elevated blood pressure, are you Nervous? Exited? Anxious? In love? This is the cool part, you get to decide.
The emotions are interpretations of physiological input from all of your bodily systems. These 4 interpretations stem from much the same physiological input. So why not choose how you are feeling. When you have an important match or meeting coming up, choose to feel excited about it instead of nervous or anxious. The physical feelings are the same. You can interpret those feelings how you choose. Decide that what you used to call nerves is excitement.
