Too little
Announce first
The timetable looks wonderful. We can check that bend later.
Presentation has displaced the small piece of work on which the demonstration depends.
Work through the awkward part; let the details count.
Readiness to sustain due care in worthwhile effort.
Diligence gives an absorbing interest the care its actual work requires. It includes checking, practicing, recording and finishing the small tasks that let an idea become dependable. A promising explanation becomes more valuable when you can follow it through an awkward example and show where it works.

The miniature railway is ready for its grand opening. Unfortunately, every carriage uncouples at the same bend. You put the ceremonial ticket aside and examine the track one joint at a time. A tiny gap has defeated an impressive amount of enthusiasm. Closing it is less theatrical than announcing the railway, and much more satisfying.
Trace a recurring fault in an unpowered model instead of polishing its presentation.

A fitting response
It separates here each time. I will check this joint first.
A bounded observation directs careful effort toward the actual problem.
Pursued too far
The train runs, but I cannot show anyone until every painted sleeper matches.
A detail with no bearing on this purpose absorbs the session and prevents a useful finish.
The railway gives the work its measure: enough care to make the promised journey possible, with a finish you can recognize.
Careful notes turn an afternoon of tinkering into something you can return to. You can distinguish the adjustment that helped from the three things you merely hoped would help. That makes a discovery easier to repeat, explain and improve.
Record the source of a date while it is in front of you; your future self should not have to reconstruct the search.
Try the beginner sequence yourself before sending it to the group.
Try the output on a few cases you can check yourself before sharing the project.
Diligence concerns the care given to work now; Perseverance concerns returning through difficulty over time.
Exactitude protects accuracy; Diligence sustains the actions needed to achieve it.
Reformatting the project log while avoiding its unresolved check is a counterfeit of Diligence. Care follows the work that matters.
Correcting an irrelevant cosmetic detail indefinitely can resemble care while preventing a useful stopping point.
Define what this session needs to establish.
Leave enough of a record to retrace your reasoning.
Finish a bounded piece before displaying it as finished.
Choose one small problem in a hobby project. Write what happens, try one relevant check, and record the result before changing another thing.

The accumulated efforts of astronomers, from the earliest dawn of civilization, have been necessary to establish the mechanical theory of astronomy. The courses of the planets have been observed for ages, with a degree of perseverance that is astonishing, if we consider the imperfection and even the want of instruments.
Mary Somerville · On the Connexion of the Physical Sciences · Introduction
Somerville describes astronomical knowledge as accumulated work across generations. The model railway asks for the same respect for small, sustained observations on an ordinary scale.
It will be of great importance to acquire a methodical exactness in working the different branches, cutting especially.
Joseph William Zaehnsdorf · The Art of Bookbinding · Chapter XV, Cutting
A craftsperson links dependable work to methodical exactness. The railway scene brings that care into a hobby: a small joint deserves attention because the whole demonstration depends on it.
My industry has been nearly as great as it could have been in the observation and collection of facts.
Charles Darwin · The Autobiography of Charles Darwin · Written May 1, 1881
Darwin names the labor of observation and collection, making the usually invisible work behind a finished account part of the story.
Formerly I used to think about my sentences before writing them down; but for several years I have found that it saves time to scribble in a vile hand whole pages as quickly as I possibly can, contracting half the words; and then correct deliberately.
Charles Darwin · The Autobiography of Charles Darwin · Written May 1, 1881
The rough draft and deliberate correction separate getting an idea down from making it dependable. Care can proceed in stages instead of demanding polish on the first attempt.
I first make the rudest outline in two or three pages, and then a larger one in several pages, a few words or one word standing for a whole discussion or series of facts.
Charles Darwin · The Autobiography of Charles Darwin · Written May 1, 1881
A rough outline gives detailed work a structure. The point for a hobby project is a usable plan of the reasoning, rather than a ceremonial display of effort.
Let us begin by a careful consideration of the creature's labours; let us support each piece of evidence by others; and then we shall be able to answer the question.
Fabre proposes supporting an observation with further evidence. The train scene likewise rewards checking the fault instead of treating an attractive first explanation as enough.
He seeks to condense much experience and much thought into a slender volume; and that is why a little book on physics contains so many past experiences and a thousand times as many possible experiences whose result is known beforehand.
The slender finished volume conceals a great deal of organized inquiry. This is a reminder that compact explanations can be the result of painstaking work.
