why is it so hard?!

Why is smiling first thing in the morning so difficult? Sometimes I just cannot do it. Its like those muscles to let me smile are paralysed. I was listening to Bradley Cooper on Radio 1 the other day and he said he writes a gratitude list every morning he wakes up. I'm going to start something like that, maybe write out the top ten things about my life every day. Maybe that way I will stop taking the good stuff for granted. Maybe that way I will be able to smile every morning. I started my job the other day. Its ok. A bit mind numbing but no stress what so ever. Thats what I wanted right....?
