Identify what is unpleasant: boredom, sensory discomfort, conflict, uncertainty, or fear of evaluation. Change the part you can—environment, sequence, tools, support, or task size.
Define a short output and a stopping point. Pair the session with a neutral or pleasant context when that does not interfere with quality.
You do not need positive feelings before beginning. The aim is a tolerable first contact and a clearer next action, not convincing yourself the task is enjoyable.
Match the change to the aversion
For boredom, use a bounded block and visible output. For sensory discomfort, change tools or environment. For conflict, prepare the message and seek support. For uncertainty, state assumptions. For evaluation fear, create an explicitly rough version.
Set a timer only after defining what will exist at the end: three invoice rows checked, one difficult email drafted, or one surface cleaned. Honor the stopping point so a small start does not become a disguised unlimited task.
This protocol is for one required, safe task whose unpleasant feature is already identifiable. If aversion repeats across different tasks or you cannot tell what is driving it, use the broader guide to task aversion. If the task is merely difficult rather than aversive, use the general guide to starting a hard task.
