My advice is always the same. I would encourage you to not seek a role. Just focus on making a difference. In doing so the role takes care of itself.
Have I ever cared about roles? Yes. It was a waste of time. Hindsight is 20/20.
Today I could care less about roles and quite frankly sometimes I'm sick of them. I'm terrible at role playing, but never tire of making a difference.
I believe it's the same for most people whether they know it or not. Roles tend to be prescribed and since God has made us all so uniquely, rare is the person who fits the prescription exactly.
Just something to think about.
