Keep physically active
If you think you are physically fit or your body needs no toning then my friend, physical exercise is not always to get your body shaped. Physical exercise is the best tip to stay active and in control of your emotions and anxieties.
It is not always for your physique but it helps you become more confident and stay more focused. It increases feelings of trust in you, and lowers nervousness and reduces stress.
You may involve yourself in some sports or in some games and mind storming activities as well. Such activities will keep you determined and help to increase your concentration level.
