Sunscreen is my number 1 2 3 4 and 5 tip. I'm a fanatic partially because I live in L.A. and have fair skin and freckles and partially because of my kids. My mom always made me wear sunscreen and I'm trying to be that mom for them.
Even if you're unhappy just pretend that you're happy. Eventually your smile will be contagious to yourself. I had to learn that. I used to think 'I'm being fake ' but you know what? Better to be fake and happy than real and miserable.
