How do you handle tackling chores that for whatever reason, you dread doing?

How do you handle tackling chores or tasks that for whatever reason, you dread doing?

I will make a set time, or date, like “at 2 o’clock, you’re going to do xyz” or “Monday is the day this is getting done.”

Right now, I have to do this task https://www.fluther.com/240019/would-it-be-weird-or-inappropriate-to-send-easter-cards-and/#quip3926063, which shouldn’t be unpleasant, yet for some reason I will put it off and put it off. I was going to do it at 2 o’clock this afternoon, but was on FB, then ate some food, and now am writing this question, all in an effort to postpone it. I need to sit down with the cards, write a quick note in each, address the envelopes and stamp. 6 or 7 cards should take not more than a half hour.

What is your tactic?
