So I think a lot about how to be a better scientist, and during my reading I found a sparkly little gem by one of the greatest experimentalists of all time, Michael Faraday. It's quoted in Analysis and Presentation of Experimental Results as above, but from Wikiquote we get the whole story:
His well-known advice to the young William Crookes, who had asked him the secret of his success as a scientific investigator, as quoted in Michael Faraday (1874) by John Hall Gladstone, p. 123
Well said. The middle part often seems the hardest for many people, in my experience: it's all too easy to work on something without finishing it, or to rush to publish something before it's really ready. The hard part is pushing through all three in the right order with the appropriate level of effort.
