we are more observant and cautious about our careers and sometimes ingore even emotions if they seem to interfere. Day and night we are more obsessed with how to find the perfect luxurious career for us since we can't do good at medeocer jobs(really not meant to offend).

However we are more interested in liberal arts than sciences or technology. We get absorbed in music, novels, art. Thats how it comes being an INFJ.
