Written affirmations are also very effective. But I have found that repeating a mantra aloud has a wonderful effect on my spirit. When I need to feel motivated, I might repeat, ‘I am inspired, disciplined and energized’ out loud two or three hundred times. To maintain the supreme sense of self-confidence I have cultivated, I repeat, ‘I am strong, able and calm.’ I even use mantras to keep me youthful and vital.
