Sometimes we stare so long at a door that is closing that we see too late the one that is open.

When one door closes, another opens; but we often look so long and so regretfully upon the closed door that we do not see the one which has opened for us.

There are two critical points in every aerial flight-its beginning and its end.

With every door that closes a new one opens.

The day will come when the man at the telephone will be able to see the distant person to whom he is speaking.

Don't keep forever on the public road, going only where others have gone and following one after the other like a flock of sheep. Leave the beaten track occasionally and dive into the woods.

We are all too much inclined, I think, to walk through life with our eyes shut. There are things all round us and right at our very feet that we have never seen, because we have never really looked.
