Your pace can belong to the task
Some things go badly when hurried because their details cannot move at the speed of your impatience. Threading a needle asks for a steadier hand, not a harsher command; you are allowed to give a delicate task the time its actual shape requires from you.
Go deeper
Let the work set a speed
Trying to force thread through a needle usually does not enlarge the eye. The task requires alignment: the thread's end and the opening must meet closely enough for one to pass through the other.
An appropriate pace comes from the demands of the work. Some tasks tolerate speed. Others involve small parts, precise placement or a surface that can be damaged by rough handling.
Before pushing yourself to move faster, identify what the task physically requires. Does a label need to sit straight? Does a fragile piece need support? Are you handling a tiny screw that could easily fall?
Allow time for that requirement rather than treating it as a personal inconvenience. A steady minute spent positioning the part may be the normal duration of doing this particular job.
