Being tall is not an identity
Being short is not an identity
Being pro-Trump is not an identity
Being anti-Trump either
Liking music is not an identity
Being smart is not an identity

Don't get me wrong: These things can be important for you.
They can be part of you you are (IN THIS MOMENT)

But
things
change
You change
People change
The world changes

And there is not ONE thing that is YOU
You are you

Doing software is not my identity, and their job shouldn't be the identity of anyone

Even if you do it in your free time, still not an identity

Do things
Like things
Love things
Embrace things
Same for hobbies
Same for people
Same for jobs
Same for all

But don't get attached

Identity is not forged on one single thing, and not at one moment either.
