The Power of Now, not Whenever!

I was brought up with "Don't put it down, put it away" so that is second nature to me. I wish I could get "Don't put off till tomorrow..." into my psyche, I'm a terrible procrastinator.

Not quite a mantra, but I came across a Phillip Larkin poem a while back and now have the last two lines written out and pinned above my desk -

We should be more careful of each other,
We should be kind while there is still time.
