Do you have a favourite prayer, or philosophical anecdote, that helps you through the day?

I have a favourite prayer, and I like those anecdotes about the importance of perseverance in the psychological and philosophical needs we all have. There are websites that provide this inspiration for the day, kind of right thinking, which I think is Buddhist or something but it helps. I am mindful that the Holy Bible says so much to fortify us in our daily struggles especially.
