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.
"If the Buddha-Nature is seen, there will be no seeing of a nature in any thing."
(Nirvana Sutra, T12n374p521b3; tr. Yamamoto)
"Neither cultivation nor seated meditation — this is the pure Chan of Tathagata."
(Mazu Daoyi, X1321p3b23; tr. Jinhua Jia)
"With sudden enlightenment to Tathagata Chan,
The six paramitas and myriad means are complete within that essence."
(Yongjia Xuanjue, T2014p395c14; tr. from "The Sword of Wisdom")
