This is a great perspective. I beleive that most of our limitations are self inflicted. We all have external limitations but we usually never hit those because we have told ourselves we can't before we even try. I truly beleive most people are not living to their full potential. This really became real to me when I started working with teams and talking to other devs and saw how they limited themselves. Then I started seeing it in myself more acutely. Its a battle to push through this.
