On 13 April 1834 Ralph Waldo Emerson wrote in his journal:
We are always getting ready to live, but never living. We have many years of technical education; then many years of earning a livelihood, and we get sick, and take journeys for our health, and compass land and sea for improvement by travelling, but the work of self-improvement, — always under our nose, — nearer than the nearest, is seldom seldom engaged in. A few, few hours in the longest life.
