It's probably better not to set goals in the first place, if you are not going to keep them, than to get in the habit of ignoring them. I make it a point now not to set my alarm clock if I don't have to be up by particular time, and if I do set it to always get up.
Similarly, I try not to set a fixed schedule for things I don't need to do at a particular time. I make a list and work on something from the list (unless something gets near a deadline). I found that having the list also helps me to avoid spinning my wheels thinking about what to work on (provided your list isn't too long, then you have to decide what to work on).
Making arbitrary "deadlines" for yourself, then ignoring them, increases rather than decreases your procrastination.
