Your post title reminds me of the adage,

Even a journey of a thousand leagues begins with the first step.

Carrying a note pad also allows you to jot down those ideas that come to you out of the blue while you're in the middle of some other task.

"I have made a deal with myself that I will make sure I do one thing (the easiest thing on the list) every day and I will not worry if I do nothing else."

Forgive yourself for not being perfect, all day, every day.

Sometimes you should just give yourself some credit for being perfect for a split second at a time.
