It's hard. Eating, drinking, traveling, wandering, doing absolutely careless things. I'm really glad I'm an Fi type and averse to "illegal" (at least as far as illegal applies OUTSIDE of the adult entertainment industry, I was sent home once from a topless bar for dancing too close to a customer) because otherwise I'd be a trainwreck.
I sometimes feel like Fi is what saves me from all that is evil and that is ill and destructive, and if I were an Se dom, I'd be some kind of soulless troglodyte.
I'm already bad at doing things I say I'm going to do (like staying off the forum).
Me and Jackson Browne go way back, though, I think Jackson Brown knows all about SP boredom, but it's Fi drawbacks (I don't ever want to see him typed as ENFP again, nor myself).
I think I'm really grateful I had nurturing parents who encouraged me to read and learn and value education, and that I do things like plan awesome trips to new places instead of doing things like snorting crystal meth.
I'm glad I want to replicate things in books, and not be a self-destructive party girl.
ISFP is like the more "intellectual" or "NF" SP though.
The ISFP is like the NF who loves wine and fine food and random sex.
People say that's the ENFP. No, it's the ISFP.
