How do you stay motivated with small wins?

Although I enjoy my own project more than my day job I often find myself less motivated than in work, as, with work, I know I'm getting a paycheck simply for getting tasks (sometimes meaningless ones) done - there's loads of small wins along the way in work and obviously I worry less about the big picture.

Has anyone else experienced/overcome this as an entrepreneur? I'd love to hear how you did it :)
