The passage argues that a firm commitment is the decisive step in any creative or ambitious undertaking. Murray suggests that before a person commits, there is hesitation and the constant possibility of drawing back, which weakens any effort. The act of committing, he contends, changes the situation and sets events in motion.

Murray drew on his own experience of organising the 1950 Scottish Himalayan Expedition, noting that booking passage to Bombay marked the point at which the venture became real. He describes how, once committed, unforeseen help and opportunities appeared that would not otherwise have arisen.

The quotation is widely cited in discussions of motivation, entrepreneurship, and personal development. It is often paired with the couplet on boldness that follows it, which Murray attributed to Goethe, though the exact wording and origin of those lines have been questioned by later commentators.

Full quotation

“At the very outset, however, no such happy course was possible. An organization had to be laid down promptly in the form of battalion orders. But when I said that nothing had been done I erred in one important matter. We had definitely committed ourselves and were half-way out of our ruts. We had put down our passage money—booked a sailing to Bombay. This may sound too simple, but is great in consequence. Until one is committed there is hesitancy, the chance to draw back, always ineffectiveness. Concerning all acts of initiative (and creation) there is one elementary truth, the ignorance of which kills countless ideas and splendid plans: that the moment one definitely commits oneself, then Providence moves too. All sorts of things occur to help one that would never otherwise have occurred. A whole stream of events issues from the decision, raising in one’s favour all manner of unforeseen incidents and meetings and material assistance, which no man could have dreamt would have come his way. I have learned a deep respect for one of Goethe’s couplets:
    Whatever you can do, or dream you can, begin it.
    Boldness has genius, power, and magic in it.”
