Hello and thank you!
Both of those are personality type indicators:
INFJ is from the Myers-Briggs Type Indicator, which puts people into 16 types based on how you observe the world and make decisions. INFJ stands for introvert, intuitive, feeling, and judging.
2w1 is from the Enneagram. Admittedly I do not know as much about this one, but it sorts people into nine main types with one subtype.
Besides writing, in my free time I like being outside. Camping, hiking, and kayaking are the best.
That sounds nice! What are some of your favorite books?
