Never underestimate the power of human stupidity.
Don't underestimate the cosmetic power of sunglasses. It's worth spending a bit of money on a quality pair. I usually go for Dior or Louis Vuitton.
You may not always have a comfortable life and you will not always be able to solve all of the world's problems at once but don't ever underestimate the importance you can have because history has shown us that courage can be contagious and hope can take on a life of its own.
Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around.
