You have to be open to change. I never stop making sure that what I say is the best of what could be said about a particular thing. It's a constant evolution. If I planted a tree one way yesterday and somebody tells me of a better way to plant a tree, I think, You know, they're right, that's better. Then I change my way to accommodate the new way of planting trees.
The political process is not tied to any particular doctrine. Genuine political doctrines, rather, are the attempt to find particular and workable solutions to this perpetual and shifty problem of conciliation.
