I never let practical considerations clutter my youthful dreams.

Man is an ape with possibilities.

These are very practical things, very important things.

I never really was much of a practical jokester or anything.

No principle ever filled anybody's milk bottle

Life's Irony; Theory says, 1+1 = 2,simple, but Practical says, 1 + 1 is less equal to 2 in the summer, & slightly greater than 2 in the winter & equal to 2 if the winter temperature is less than -1 degree.
