The Zen question of 'If not Now, When?' I interpret also as Can you be happy in the process?

It can be miserable, 'hard', if you havent surrendered to it.... if you are still caught in the what Eckhart Tolle calls the 'pain body'. It is that aspect of the analytical mind/ego that is still trying to control so it won't die. The attachment to the past as a definition of self and the attachment to the future as an addiction to fear or wishing keeps it alive and in control becuase it is trying to protect you and help you survive...though killing you slowly in the process.
Be in the Now and just be happy with where you are knowing that you don't have to stay there. You can create yourself in the present constantly.
