How do I let go of my ‘corporate’ personality and find my real self?

I am too selfless, don't have boundaries, don't have ego, but I am going to always put everyone in my shoes whenever I get a chance.
I developed this arrogance when I started living on my own, which is my greatest flaw, but unable to fix it.
I am unable to fix it because it kills a part of my personality which helped me to get a job.
I want to find some new way to stop this corporate personality to come out when I am with my friend, family, classmates etc.

My whole personality is my old job which I have left. I need to get rid of it to find love for myself.
