Uhhhh, I've never heard INFJs described as "super artsy". That's ISFP. (Also, the term artsy fartsy should be firebombed. No, rilly! Hahaha!)
NTs are stereotyped as being "technically skilled and focused".
INFJs are usually stereotyped as writers and readers. We are also focused on humanity. Being focused on "humanity" doesn't necessarily mean we love being around people, even if we're good with people.
INFJs are Ni Fe Ti Se.
Here are our top abilities from strongest to weakest
Introverted: We are charged by alone time and being too social drains our energy.
Ni: Looks at consistency of ideas and thoughts with an internal framework. Trusts flashes from the unconscious, which may be hard for others to understand.
Fe: Seeks harmony with and between people in the outside world. Interpersonal and cultural values are important.
Ti: Seeks internal consistency and logic of ideas. Trusts his or her internal framework, which may be difficult to explain to others.
Se: Acts on concrete data from here and now. Trusts the present, then lets it go.
We're big-picture oriented. While we can certainly learn to be detail-oriented, and may even obsess over it, it is never our strongest ability, and big-picture thinking will always dominate.
We're stuck in our heads. Despite Se being in our top 4 functions, it's "inferior". We have trouble "living in the moment".
We like to connect things. Our brains are like investigation boards in crime movies. We like symbolism, and we even see symbolism when they weren't intended.
We're future-oriented.
We're non-confrontational. We like harmony.
We don't work well in groups.
So, something really funny about INFJs is that we're not the ideal office worker by a long shot. We don't do well on teams or working in groups. We aren't naturally detail-oriented. We're good with people, so we're placed in people-oriented roles, which burns us out because we're introverts. A few years ago someone posted about how INFJs are often low achievers (underpaid, passed over for promotions) at their jobs. This is part of what makes MBTI important. It helps us find the right jobs. We're better at being part of the idea engine at a job than doing detail-oriented work like data entry, measuring, technical skills that don't allow for mistakes, etc. We can absolutely learn to be detail-oriented, but any time you choose the opposite of what you're naturally better at, there will be fallout. So if you choose a detail-oriented profession you may get stressed out more easily, or you'll be less personable, or burn out and need even more alone time after work to recoup, or maybe you'll get defensive if someone questions your detailed work.
Another interesting thing about INFJs a lot of people overlook is that Fe makes us want to go along with society. You know those people who care about what other people think and want to fit in? Those are Fe users. At the same time, Ni makes us naturally different than others. We're independent thinkers, we have a hard time explaining how we think because Ni and Ti are pointed more inward and we can't always articulate the path to our ideas. So, INFJs are also naturally independent, "different", and can be rebellious. (Though, we hate confrontation and being publicly embarrassed, so too much rebellion is also uncomfortable.) So, INFJs are sort of always at war with ourselves over whether it is better to go along, or be independent and we try to strike a balance. We don't like to be leaders or followers. We like to be on the sidelines doing our own INFJ thing. (There are a lot of famous INFJs who were great leaders, but they fell into those roles because they were visionaries and had big ideas about, usually, making the world better.)

So, me specifically:
I'm an artist and writer. My work is full of symbolism and about ideas, and possibilities about a better future.
Cultural values and harmony are important to me. Order (quiet discord) is less important to me than achieving true harmony (even sometimes at the expense of non-confrontation, though confrontation makes me cringe.)
I am usually good with people, but they drain me.
I like hanging out with animals, as well as some people sometimes, and reading, hiking, going to see live music, going to museums and galleries, discussing ideas, and gaming. I like to run, ski, bike, hike, and other sports that aren't team-oriented.
I hate any activity where I'm supposed to be the center of attention, whether it is sports, games, karaoke, being in a band on stage, public speaking, etc.
