If you feel down today and things just aren't going your way, like I don't know, maybe Dublin City Council shut off your water this morning even though they claimed the water will be on at 7 in the morning, you know, things like that,  just remember the lesson we should all take after watching this little guy.

Never give up. Even when you repeatedly fail at something, have a rest, have a think, come back and try again. To stretch out the water failure analogy that would have meant going back to bed until the water came back on this morning but then who would have provided you with this link to a mouse battling a cookie.

Lesson learnt today, don't trust Dublin City Council and mouse > cookie.
