Absolutely. There's seems to always be this interesting duality to achieving anything difficult.

You have to have faith that you can do well, but you also have to acknowedge the hard facts of reality.

You have to be kind, but you also have to be firm and not a pushover.

You have to help people, but you can't be taken advantage of.

You have to get out of your comfort zone, but you have to avoid burnout.

So on and so forth.
