A new tradition is easy to begin. If you have lived by yourself for three weeks and done the same thing each Saturday afternoon, then a new tradition has begun.
Each Saturday I take a long walk to the city and back. I generally have a contrived purpose for the walk and it fills three hours of my day.
On the way home I feel so virtuous and well exercised that I stop at the local French themed cafe and buy myself two pistachio macarons.
One should never mess with tradition.
