For we have always understood that when times change, so must we, that fidelity to our founding principles requires new responses to new challenges, that preserving our individual freedoms ultimately requires collective action.
Whenever I look at the history of presidents I deeply admire - the one thing that I'm always struck by is persistence. It's a quality that's underrated. Being able to plough through, being able to stay buoyant in the face of challenges.
Our problem is that we often expect instantaneous solutions to such challenges, forgetting that frequently the heavenly virtue of patience is required.
So long as I'm the president, we will. I clearly see the challenge. I see the challenge of what these threats pose to our homeland, and I see the challenge of what these threats pose to the world.
Courage is resistance to fear, mastery of fear - not absence of fear. So many look to eradicate fear from their lives, when that is an impossible task. You can certainly experience moments in absence of fear, however accept that fear will be with you whenever you are in the process of living creatively. The challenge is to go ahead regardless, simply notice the feeling and manage being courageous.
Every day, there's that tension and the pressure. Each scene that you shoot is like getting to that next step, but there's still that mountain to climb. So it's not like one day is harder or one scene is harder. They are all equally challenging.
