“What a waste of beauty, what a waste of knowledge a sudden death can inflict, like spilling something vital away into dry soil.”

“Slowly the poison the whole blood stream fills.It is not the effort nor the failure tires.The waste remains, the waste remains and kills.It is not your system or clear sight that millsDown small to the consequence a life requires;Slowly the poison the whole blood stream fills.They bled an old dog dry yet the exchange rillsOf young dog blood gave but a month's desires.The waste remains, the waste remains and kills.It is the Chinese tombs and the slag hillsUsurp the soil, and not the soil retires.Slowly the poison the whole blood stream fills.Not to have fire is to be a skin that shrills.The complete fire is death. From partial firesThe waste remains, the waste remains and kills.It is the poems you have lost, the illsFrom missing dates, at which the heart expires.Slowly the poison the whole blood stream fills.The waste remains, the waste remains and kills.- 'Missing Dates”

“There is a certain elegance in wasting time. Any fool can waste money, but when you waste time you waste what is priceless.”

“...the beautiful thing--perhaps the thing I love most about the gospel-- is that everything we learn we can use and take with us and use it again. No bit of knowledge goes wasted. Everything you are learning now is preparing you for something else. Did you know that? What a concept!”

“Knowledge that is not used is often wasted, and it is shameful to waste anything, especially anything as valuable as knowledge.”

“Leela: Why are we listening to them? It is a waste of time.The Doctor; It is difficult to know what will be a waste of time until after the time has been wasted, by which time it is too late. So predicting what will be a waste of time is something of a waste of time. Unless it gives you pleasure of course when it probably doesn't count as a waste of time.Leela (yawning): I am sorry I did not hear what you said, Doctor.The Doctor (smiling): That was a waste of time then.”
