Through loyalty to the past, our mind refuses to realize that tomorrow's joy is possible only if today's makes way for it; that each wave owes the beauty of its line only to the withdrawal of the preceding one.

A straight path never leads anywhere except to the objective.

It is not always by plugging away at a difficulty and sticking to it that one overcomes it; often it is by working on the one next to it. Some things and some people have to be approached obliquely, at an angle.

I had a huge advantage when I started 50 years ago - my job was secure. I didn't have to promote myself. These days there's far more pressure to make a mark, so the temptation is to make adventure television or personality shows. I hope the more didactic approach won't be lost.
