Our reading
An editorial interpretation.
The speaker contrasts stopping from tiredness with stopping after completion. The difference becomes a claim about personal determination: finishing the task is presented as the decisive measure. Its blunt comparison with most people gives the statement the tone of a confident, uncompromising self-description.
