It's a good beginning. Then stop being attached to non-attachment. And finally, don't create a concept of not being attached to non-attachment. So says Baizhang.
"While teachers of the middle way, mind only, transcendent wisdom, mantra, and other schools may have their own assertions, the fulfillment of those intentions is the same. There is not a single thing that is not contained within mind." (Gampopa to Düsum Khyenpa, in "The First Karmapa", KTD Pub, p 254)
Being patient is good. Waiting for enlightenment is delusion and incorrect practice. The patience to practise in Zen is, however, the patience of non-production of phenomena (anutpattika-dharma-ksanti). That is seeing emptiness without fear, letting go without worry.
