No gains without pains. 吃得苦中苦方为人上人。 A little wind kindles,much puts out the fire. 适可而止,过犹不及。 A journey of a thousand miles begins with a single step. 千里之行始于足下。 An hour in the morning is worth two in the evening. 一日之计在于晨。 An idle youth,a needy age. 少壮不努力,老大徒伤悲。 Progress is the activity of today and the assurance of tomorrow. 进步是今天的活动,明天的保证。
