There are only two mistakes one can make along the road to truth: not going all the way, and not starting.
– not The Buddha, and frequently misattributed
Perhaps derived from
My advice to you is not to undertake the spiritual path. It is too difficult, too long, and is too demanding. I suggest you ask for your money back, and go home. This is not a picnic. It is really going to ask everything of you. So, it is best not to begin. However, if you do begin, it is best to finish. – Chögyam Trungpa
or perhaps from
No matter; the Road has two rules only: Begin and Continue, and the Buddha left us a detailed guide-book for the Way. But it must be trodden, every weary step of it. There is no by-pass nor ever will be, and no short cuts whatever. We tread it on our own two feet, alone, yet feeling in the darkness a million more ahead of us, beside us and behind. There is no chance nor luck nor fortune, good or bad, upon the Way; each moment, each event, is the net result of a million causes each of own own fathering. – Christmas Humphreys, A Western Approach to Zen (1971)
