Essential Backblip?

Got in trouble with a friend for blipping my cat too often, and when I explained that I do it if I haven't managed to find a good blip that day, he asked why I don't just leave that day blank.
We got into a chat about the nature of wanting to blip every day and why - and the fine line between blip being a challenge or a chore.

How about you blippers - do you feel the need to blip every single day?
How do you feel if you miss a day, and how much does blip encroach on your everyday life?
