It happens all the time, we carry a task along for days, weeks, months. We focus on absolutely anything else that is not the task, we don’t want to do it. Many times the task is inconsequential, send an email, go to the bank, put a picture on the wall. But we don’t do it and days and weeks go by and we drag the task along.
Why do we do it? I would take a relatively small amount of time to just do it and get it out of the way, but we prefer to leave it hanging on our minds, spending our precious cognitive energy to keep it on our subconscious to-do list.
Beat the resistance, get it out of the way, it will be worth it.
