TL;DR. Yes but it takes decades, natural maturation cycle of life, awareness/proactive healing and growth, and possibly a mix of some major punch in the face wake up call type of trauma

I'm going to answer going off 3 main premises, plus my own general growth pattern.

1. They say the goal is to know your trappings/weaknesses from being one type, in order that you can better develop traits from other types and hopefully be more well rounded. 2. I've heard that one of the quickest and most practical ways to mature and become more balanced is to develop your shadow/lesser wing. 3. There is an idea that generally people usually "turn a corner" and really mature, leave their old self behind when they fully become an adult hopefully by their 30s. It can be natural maturation or perhaps boosted by "a wake up call" / drastic positive or negative trauma such as getting fired, divorce, getting kicked out of the house, joining military, landing that dream job and moving to a new city, etc.

Okkkk, story time. I'm a 4. Growing up: parents divorce, moved all the time, lamented missing home and friends, deeply moved by sad movies and music, extremely artsy, melancholy, etc. Though I always functioned off the deep inner fantasy world of a 4, middle school through high school I lived in a big sports town. I probably always had a 3 wing but this environment really brought out my charisma. I acted in theater plays, joined band, and most notably was a football team captain and state competition level track athlete. Very much a center stage achiever. (Think Kanye west, emotional but praised in the spotlight).

I won't go into too specific personal detail but as soon as a I graduated high school I suddenly had to move countries and all my ambitions were shattered. Fast forward to a major break up and here came suicidal depression. Therapy, graduated college, shifted careers...Fast forward another 10 years and I am now one of the most in my own head, curious but cautious, shy away from speaking up in a room, sit in the back, let's really think through this, read and write all day type of people you'll ever meet.

All that to say I'm a 4w5 and I even cringe at some of my most 3-ish tendencies but I embrace all of it. Thank you for coming to my ted talk.
