I have been noticing for many years now that I have trouble finishing a job - the last 5-10% of it. I will frequently (not always) stop and postpone or experience discomfort as if the last 10% is as difficult as, say, the previous 40%. This then results in either anxiety (if I postpone) or tiredness (if I expend too much psychological energy).
This could be while running, washing dishes, tapering off smoking, a work-task, meditating, anything really.
While running, my cousin makes a point of going maximum effort in the last stretch. Is this a good way (in all contexts)?
Do you experience this phenomenon? Any sage advice on how to make finishing tasks easier?
