Are you even interested in the PhD or in the subject itself? I think if not, then no internal motivation works. I tend to think of myself as a really internally motivated person, as I have a various hobbies that I cultivate that requires disciplines in muscular and mental side. But I am interested in all of those hobbies, and I never dread the moment where I have to train, practice, or study related to those subjects. No end goal in sight for me, it is purely for internal enjoyment. Maybe one day create a youtube/instagram channel for fun and showoff but that's about it.
