He that embarks on the voyage of life will always wish to advance rather by the impulse of the wind than the strokes of the oar; and many fold in their passage; while they lie waiting for the gale.

What a strange narrowness of mind now is that, to think the things we have not known are better than the things we have known.

We seldom require more to the happiness of the present hour than to surpass him that stands next before us.

I am far from any intention to limit curiosity, or confine the labours of learning to arts of immediate and necessary use. It is only from the various essays of experimental industry, and the vague excursions of mind set upon discovery, that any advancement of knowledge can be expected; and though many must be disappointed in their labours, yet they are not to be charged with having spent their time in vain; their example contributed to inspire emulation, and their miscarriage taught others the way to success.

He that condemns himself to compose on a stated day will often bring to his task attention dissipated, a memory embarrassed, an imagination overwhelmed, a mind distracted with anxieties, a body languishing with disease: he will labour on a barren topic till it is too late to change it; or, in the ardour of invention, diffuse his thoughts into wild exuberance, which the pressing hour of publication cannot suffer judgment to examine or reduce.

The insolence of wealth will creep out.

Idleness is often covered by turbulence and hurry. He that neglects his known duty and real employment naturally endeavours to crowd his mind with something that may bar out the remembrance of his own folly, and does any thing but what he ought to do with eager diligence, that he may keep himself in his own favour.
