A man who dares to waste one hour of time has not discovered the value of life.
Bahia, Brazil
I had, during many years, followed a golden rule, namely, that whenever a published fact, a new observation or thought came across me, which was opposed to my general results, to make a memorandum of it without fail and at once; for I had found by experience that such facts and thoughts were far more apt to escape from the memory than favourable ones.
Lost Time is never found again.
It is not that we have a short time to live, but that we waste a great deal of it.
He who does not value life does not deserve it.
