The secret of being miserable is to have leisure to bother about whether you are happy or not. The cure for it is occupation. 痛苦的本因在于你有闲暇考虑你是否幸福,而治愈痛苦的诀窍是辛勤工作。
If you would go up high, then use your own legs! Do not let yourselves carried aloft; do not seat yourselves on other people's backs and heads. 如果你想走到高处,就要使用自己的两条腿!不要让别人把你抬到高处;不要坐在别人的背上和头上。 — 尼采
