I have noticed that often when contemplating some task I will feel reluctant considering it more like a chore but then passing by the thing if I pick it up before I know it I'm enthusiastically involved. This tells me the emotion leading to procrastination was born of thoughts of little value.
So now I tend to not wait for the proper mood to come along. Example: I'm sitting watching a good tv show but I know the yard needs mowing/ it's time for piano practice. I don't feel like doing any of that but now I realize my mood has little substance. The next step is to just get up and walk around a little. This will generate a different line of thinking. Now I can go to the task at hand knowing that all I have to do is just start with the first few movements and quite likely I'll soon be sucked into the project.
The lesson: you can ignore how you feel. Those thoughts come from junk irrational thinking. Just clip them off when you first notice them. The key is to keep busy.
The other day we were working at the local mental health facility and I overheard one client an overweight teen describing his moods to his therapist how he doesn't feel like doing this or that but then later when it's too late to do much he then gets enthusiastic. I wondered if they would talk about or wrestle with those moods. At my age I've learned some life lessons.
