Too little
Drop the question
That handwriting defeated me once. There is no reason to return.
One unsuccessful attempt closes a question that another approach might illuminate.
Return to the inquiry with something learned.
Readiness to continue worthwhile effort through setbacks.
Perseverance sustains a worthwhile effort through difficulty and setbacks. Returning is an active decision: you carry forward what the earlier attempt taught you and try again with a reason to continue. A long inquiry gains shape through these returns, even when no single session looks impressive.

Your first attempt to read the old handwriting produced a sentence about a very unlikely cheese. On the next visit you compare the troublesome letter with three clearer examples on the same page. The cheese disappears. You have not become an expert overnight, but your second attempt knows something your first one did not.
Resume study using a better method after an unproductive attempt.
Too little
That handwriting defeated me once. There is no reason to return.
One unsuccessful attempt closes a question that another approach might illuminate.
A fitting response
These three clear loops may explain the unclear one.
The return carries forward an observation and changes the method.
Pursued too far
I will keep reading this as cheese until it finally makes sense.
Persistence in a preferred reading replaces the inquiry it was meant to sustain.
Returning is most fruitful when each attempt carries something learned from the last. The method can change while the question stays alive.
Repeated visits let separate clues accumulate. A letter you could not read last week becomes recognizable after seeing it elsewhere; a question that seemed blank acquires a starting point. Your earlier work remains available to the next attempt.
Keep the route that failed and why it failed, then choose a different starting assumption.
Return to a short passage you once found difficult and notice the phrases that have become intelligible.
Patience allows learning time; Perseverance keeps a worthwhile inquiry alive across difficult intervals.
Discernment helps decide whether the pursuit and the method still deserve your effort.
An identical attempt without attention to what failed can imitate Perseverance while learning nothing.
Past effort alone does not make another month worthwhile. Reconsider the purpose as well as the method.
Leave the next small question visible when you stop.
Retain useful failures in a compact record.
Review whether the pursuit still matters to you.
Return to a small unresolved question you still care about. Keep one useful observation from your earlier attempt and change one part of your approach.
A hobby can be paused or ended without becoming a character failure. Keep effort within your available capacity.
Seven selections to return to through the week. Follow a source link to read the surrounding passage.
It is the completion of a short paper read before the Geological Society more than forty years ago, and has revived old geological thoughts.
Charles Darwin · The Autobiography of Charles Darwin · Written May 1, 1881
Darwin returns to an inquiry begun decades earlier. The long interval belongs to this particular history; the useful parallel is that an earlier question can remain available for renewed attention.
I think that I have become a little more skilful in guessing right explanations and in devising experimental tests; but this may probably be the result of mere practice, and of a larger store of knowledge.
Charles Darwin · The Autobiography of Charles Darwin · Written May 1, 1881
Practice and a larger store of knowledge change the next attempt. Reading an old letter again is worthwhile when the return brings better comparisons, rather than merely repeating the first guess.
After we have reached the conclusion, a reconsideration of the steps of the process to see what is helpful, what is harmful, what is merely useless, will assist in dealing more promptly and efficaciously with analogous problems in the future.
John Dewey · How We Think · Judgment: The Interpretation of Facts
Reviewing which steps helped makes later inquiry more capable. The corrected reading preserves a method that can be used again, not just the satisfaction of reaching an answer.
Projection and reflection, going directly ahead and turning back in scrutiny, should alternate.
John Dewey · How We Think · Some General Conclusions
Forward work and backward examination alternate. This fits returning to the manuscript with clearer examples instead of treating uninterrupted effort as the only form of persistence.
We slowly learn that life consists of processes as well as results, and that failure may come quite as easily from ignoring the adequacy of one's method as from selfish or ignoble aims.
Jane Addams · Democracy and Social Ethics · Introduction
Addams discusses the methods of social action, not hobby technique. Her distinction between worthy aims and adequate methods helps explain why renewed effort should also reconsider how it proceeds.
But all my efforts only served at first the better to show me the difficulty, which indeed was something.
Poincaré counts a clearer understanding of the difficulty as something gained. The passage permits an unfinished attempt to yield useful knowledge without pretending that effort guarantees success.
Now, the greatest mistakes and faults with regard to candles, as in many other things, often bring with them instruction which we should not receive if they had not occurred.
Michael Faraday · The Chemical History of a Candle · Lecture I, The Flame
Faraday finds instruction in the fault itself. The unlikely cheese in the handwriting scene can play a similar part: a mistaken reading reveals which shapes need another comparison.
