We should forget, day by day, what we have done; this is true non-attachment. And we should do something new. To do something new, of course we must know our past, and this is all right. But we should not keep holding onto anything we have done; we should only reflect on it.
And we must have some idea of what we should do in the future. But the future is the future, the past is the past; now we should work on something new.
“This is our attitude, and how we should live in this world.
–Shunryu Suzuki, Zen Mind, Beginner’s Mind
