Most are engaged in business the greater part of their lives, because the soul abhors a vacuum and they have not discovered any continuous employment for man's nobler faculties.

Only he is successful in his business who makes that pursuit which affords him the highest pleasure to sustain him.

Things do not change; we change.

All change is a miracle to contemplate; but it is a miracle which is taking place every second.

We perceive and are affected by changes too subtle to be described.
