If your positive outlook flows from finding silence within yourself then it is authentic, true and a powerful tool. But if it’s force-fed from the morning mirror "Go get ‘em tiger" falsehood or the mask wearing of "I’m fine, I’m fine! Life is good.” then it will undermine you. Find this inner peace and let it be the backdrop of your good thoughts; it’s more 'tuning in' to what you know than painting cracks with pained smiles on top.
