Never idle a moment, but thrifty and thoughtful of others. [ Longfellow ]

All thoughtful men are solitary and original in themselves. [ Lowell ]

Education is the only interest worthy the deep, controlling anxiety of the thoughtful man. [ Wendell Phillips ]

The heavens and the earth, the woods and the wayside, teem with instruction and knowledge to the curious and thoughtful. [ Hosea Ballou ]

There is only one cure for public distress, and that is public education, directed to make men thoughtful, merciful, and just. [ John Ruskin ]

A man or a woman may be highly irritable, and yet be sweet, tender, gentle, loving, sociable, kind, charitable, thoughtful for others, unselfish, generous. [ Charles Buxton ]

When the wandering demon of Drunkenness finds a ship adrift - no steady wind in its sails, no thoughtful pilot directing its course - he steps on board, takes the helm and steers straight for the maelstrom. [ Holmes ]

Exaggeration is neither thoughtful, wise, nor safe; it is a proof of the weakness of the understanding, or the want of discernment of him that utters it, so that even when he speaks the truth, he soon finds it is received with large discount, or utter unbelief. [ W. B. Kinney ]

From numberless books the fluttering reader, idle and inconstant, bears away the bloom that only clings to the outer leaf; but genius has its nectaries, delicate glands, and secrecies of sweetness, and upon these the thoughtful mind must settle in its labor, before the choice perfume of fancy and wisdom is drawn forth. [ Willmott ]

The fact is, that of all God's gifts to the sight of man, color is the holiest, the most divine, the most solemn, We speak rashly of gay color and sad color, for color cannot at once be good and gay. All good color is in some degree pensive, the loveliest is melancholy, and the purest and most thoughtful minds are those which love color the most. [ Thomas Starr King ]
