The day may seem dreary, cold and wet, or you can consider it to be an opportunity to get cozy.
One bad experience may turn your whole day being bad, or you can isolate it and see that everything else seems rosy.
You have a blemish on your chin, but your hair looks nice and shiny.
Every single red light is stopping you along your way, but you could relax and realise that the importance is not really about timing, but that you will actually be arriving.
It's all about how you see things.
You could let that person rub you up the wrong way and make you feel bad, or you could consider their tactics ridiculous and laugh it off.
I like to imagine sometimes that my life is a movie, or a sit com, and each encounter is a scene. Make it entertaining by adding some interesting or hilarious narration for the audience, which is me. It works. Suddenly life isn't so serious, and can be quite entertaining.
The world is what we make of it, so get creative and change what you don't like. It's all in the mind.
