I would say the I**J types probably have the most difficult time adapting but they will do so if you explain it to them, give them motivation, then leave them alone to make the decision themselves.

There are some situations as a 'p' type I don't adapt well to. Like being stuck in a place with strict rules and schedules or being in an environment that I felt a great deal of unnecessary rules. I will adapt, but I won't be all that happy doing it and will slip up at the first opportunity (sometimes on purpose).

Because of my personailty, in situations like that, I will actually try to change the situation to adapt to me and if I can't, will eventually leave it.
