A professional is an imposter.
There is no true professional, to begin with. There is only acting like one.
You sit down to work on time, like a professional.
You do the work despite not wanting to, like a professional.
You show up, day after day, countering the voice inside your head, like a professional would.
No one will assign you professionalism or leadership like they assign designations in schools and organisations.
We become self-assigned professionals just because we act like them.
