Through life you will be addicted to taking on different identities. Attending a well done Independence Day celebration will urge you to declare "I am a Patriot". Moderate technical skills will want you to keep repeating to unsuspecting strangers that "you are engineer". This desire to take on a identity and nurture that starts innocently, becomes addictive and left uncontrolled is a major source of angst.
A good way to spot the identity that you are currently obsessed with is to examine conditions under which your ego is badly hurt. For instance, many people struggle when they are fired from a Job. The financial impact of that is real. However, the stinging pain is due to the invalidation of identity that you have carefully nurtured.
In fact, a good portion of life is spent on reaffirming and validating this identity. Just see the tag lines on LinkedIn or the number of posts that start with "Incredibly proud ...". The moment you fall into the trap of writing posts that start with "Honored to be ...", "Incredibly proud ..." etc. you are in trouble. As you have in that act, watered this “identity beast” that each day wants more.
This identity does not lead to mastery. In fact, I am going to be bold enough to suggest this identity has no useful purpose. It leads to a fixed mindset, it takes enormous energy to sustain and it is brittle - the slightest threat causes deep lasting pain.
To reduce the grip of this trap, first see identities for what they are:
You are not an Engineer. Instead, you have cultivated certain skills that pay well.
You are not a Parent. Instead, you have this wonderful experience to learn, laugh, love and get annoyed with a small human.
You are not a Patriot. Instead, you believe in the superiority of people who live in a bounded region in the world and have cultural similarities to you.
Then after reducing your identity’s hold on you, if you still feel compelled to assume one, take on one that is benign. For instance, the identity of a "Learner" is a good one to take on as almost all things that happen to us are learning opportunities. So it is more resilient and requires little external validation.
Eventually, when this addiction of forming and nurturing identities has lost its grip on you, shed all identities. Resist temptations to take a new one and to nurture it. Live a life of lightness without this unnecessary baggage of identity.
