Kathy and I spent this weekend having a brief stopover in New York before heading to San Diego.

One thing we'd really been looking forward to was a visit to the Guggenheim museum. It didn't disappoint.

In addition to the usual exhibits, they had a fascinating feature on the conceptual artist On Kawara.

It included all of his major pieces, from his date paintings done over 48 years to his “one million years” list of the million years preceding the creation of the idea.

What really caught my attention were his postcards. Over decades he sent a variety of postcards daily to friends round the world all focused on specific ideas. One set listed all the places he'd visited that day. Another the people he'd met.

For one series he sent postcards every day for twelve years listing the time he got up that day.

Now you might argue it takes a very strange mentality and obsessive nature to create works like that.

But what I found interesting was the discipline he applied to send two to three postcards every day for 12 years. It didn't matter what the weather was like, whether he was ill, had others things to do or was travelling the world.

Every day for twelve years he sent those postcards without fail.

I've got to believe that if a conceptual artist can be disciplined enough to send a handful of postcards every day for over a decade then the rest of us  should be able to manage a few emails a week, or phone calls to clients or any other form of follow-up.

Let's be honest, the rewards are more tangible and immediate for us than for an artist.

All it takes is the application of a little discipline and those rewards can be ours.

If he can do it, so can we.
