青年霍格森，在山坡上放羊時讓他那繁忙的大腦處於休眠狀態，而不是花費心思計算星星的位置，他將不會成為著名的天文學家。

勞動改變一切——不是斷斷續續、變化無常的或者方向偏差的勞動，而是忠誠的、不懈的、方向正確的日夜勞動。正如，要想獲得自由，必須時刻警惕；而要想獲得永久的成功，則必須堅持不懈地工作。

If　I　Rest；　I　Rust

Orison　Marden

The　significant　inscription　found　on　an　old　key—“If　I　rest；　I　rust”—would　be　an　excellent　motto　for　those　who　are　afflicted　with　the　slightest　taint　of　idleness。　Even　the　industrious　might　adopt　it　with　advantage　to　serve　as　a　reminder　that；　if　one　allows　his　faculties　to　rest；　like　the　iron　in　the　unused　key；　they　will　soon　show　signs　of　rust；　and；　ultimately；　cannot　do　the　work　required　of　them。

Those　who　would　attain　the　heights　reached　and　kept　by　great　men　must　keep　their　faculties　polished　by　constant　use；　so　that　they　may　unlock　the　doors　of　knowledge；　the　gates　that　guard　the　entrances　to　the　professions；　to　science；　art；　literature；　agriculture—every　department of　human　endeavor。

Labor　vanquished　all—not　inconstant；　spasmodic；　or　ill…directed　labor；　but　faithful；　unremitting；　daily　effort　toward　a　well…directed　purpose。　Just　as　truly　as　eternal　vigilance　is　the　price　of　liberty；　so　is　eternal　industry　the　pr
