7Is your glass half-empty or half-full? Answering this age-old question may reflect your outlook on life, your attitude toward yourself, whether you're optimistic or pessimistic, or it may even affect your health. Studies show that personality traits such as optimism and pessimism play a considerable role in determining your health and well-being. The positive thinking that comes with optimism is a practical part of stress management. Positive thinking in no way means that we keep our heads in the sand and ignore life's less pleasant situations. Instead, you have to approach the unpleasantness more positively and productively. Always think that something best is going to happen, and ignore the worst-case scenarios. Stop getting in your way and focus instead on what you can achieve right here right now!
