To get myself to do a job I'll tell myself that I don't actually have to do the task but I do have to put on my work gloves and shoes and go over and stand in front of it. Then, because I'm ready to do it, I tend to continue and next thing you know my recycling is all sorted or my wood is stacked. Usually I get quite a bit done with that technique. If I just commit to the first step and give myself permission to give up I usually complete the job.
