Muchas cosas difíciles de diseñar suelen ser fáciles de realizar.
Samuel Johnson
What is written without effort is in general read without pleasure.
Samuel Johnson, Johnsonian Miscellanies – Vol II
Mankind have a great aversion to intellectual labor; but even supposing knowledge to be easily attainable, more people would be content to be ignorant than would take even a little trouble to acquire it.
Samuel Johnson
