I can plod. I can persevere in any definite pursuit. To this I owe everything.

We have only to keep the end in view, and have our hearts thoroughly engaged in the pursuit of it, and means will not be very difficult.

Have a definite opinion.

I just realised I'm the adult and I have to be strong. I didn't want to plod along in a numb state, I needed to be totally aware of what's going on, otherwise it wouldn't be fair.

There is reverence that we owe to everything in human shape.

To it, more than to anything else, I owe whatever success I have had -- to this power of settling down to the day's work and trying to do it to the best of one's ability, and letting the future take care of itself.
