I consistently score INTJ, and I match the description mostly, but from that description and others it seems if you are an INTJ you are always confident in your ability, able to keep at something and never second guess themselves. But I do a lot. i have social anxiety and often feel down about my own ability to achieve both socially and academically, and I sometimes have so little motivation to do anything. Is this normal or at least an occasional occurence for an INTJ? All the INTJs on here seem a lot mentally stronger than me.
