"Stress is the trash of modern life - we all generate it but if you don't dispose of it properly, it will pile up and overtake your life" - Danzae Pace
Always respect your limitations. Acknowledge when things are getting too much that you can't handle it, or if they are not pushing you to the best of your ability. Having too much stress is not healthy, but having too little doesn't help you grow. Make sure you find that balance in your life, and always strive to maintain that balance.
