"The habits of study acquired at Universities are of the highest importance in after-life. At the season when you are in young years the whole mind is, as it were, fluid, and is capable of forming itself into any shape that the owner of the mind pleases to order it to form itself into. The mind is in a fluid state, but it hardens up gradually to the consistency of rock or iron, and you cannot alter the habits of an old man, but as he has begun he will proceed and go on to the last."
