I was when I was exiled.

Not that I was happy being exiled, no. No TARDIS. Trapped in one era. Used as military sounding board.

But I found people, and those people helped me through it and were there for me afterwards. You don't do what you do because of prison. You constructed your life around the people you hate before you even came to the ship. You have so much potential. You gave your sister strength. You save lives. You can motivate masses.

But you waste your time and energy and words on things you hate and then forget that you pull people and things you care about in with you.
