How do you achieve and maintain a sense of self-actualization?

I find myself (23M) often falling into month-long periods where I am essentially going through the motions, getting the bare-minimum completed. And I’ll “wake up” and think “I have done nothing meaningful for four months”. Do any of you struggle with this, and is there something in the INFJ type which makes this more likely to occur? And how might it be avoided? What habits do you have to keep you grounded in your self-actualization needs?
