For me it is the chore factor, the feeling that it's something bothersome that has to be done. One way around that I've found is to convert it to a desire - saying to myself "I deserve clean, healthy teeth" is enough motivation, for me, to pick up the floss. Similarly, "I deserve a clean, tidy home" gets me picking up the vacuum and mop, "I deserve a healthy body" is a useful mantra for eating well and exercising.

Very true. For me, it is the feeling of 100 small 2-minute things. I find myself looking how to get out of as many as possible.

To me it goes like this; I just did it yesterday, there’s nothing there to get out. So I’d forget about it for another week.
