I have a sticker on my mirror that says 'you're my favourite' on it. And each morning, before I blow-dry my hair, I look at the sticker, smile at my reflection and repeat what it says while staring myself in the eye. It sounds cheesy, and trust me, I've gotten some weird looks from Jon, but in the long run, it's been worth it.

You see, there's no one in the whole world who is harder on me than myself. I suspect it's the same for you -- all too often, we are our own worst enemies. It seems like we're wired to be critical of ourselves.

But there's no limit to the benefits that self-confidence and positive self-talk can have on both your emotional and physical health. It's not easy to change your behaviour, and the key is to start slow. Every day, while you're primping in front of the mirror, make an effort to say one nice thing to yourself. As for me, I have my sticker to remind, and it does, every day.
