I'm not going to go through with the plan
Are you not interested in the plan?
I hate it and I'm not in the mood to do it.
I think you should push through and go ahead with the plan. You may not feel like it now, but once you're finished, you'll be relieved.
Nah I wanna drop it since I don't feel like it.
You should tell them what you plan to do then. People might be counting on you to go through with it.
