i was finding the topic of our eng group discussion and i found this -->

Pursuit of Happiness

You won't gain knowledge without being there,

You won't gain respect without playing fair

You won't gain courage without facing fear,

You won't gain strength if you don't persevere,

You won't gain wisdom without making the mistake,

You won't gain truth by being fake,

You won't gain love without holding one near,

You won't gain happiness without a tear

by Bonnie Van De Ven

so meaningful..expecially You won't gain wisdom without making the mistake as 人谁无错,只要回头是岸,放下屠刀,立地成佛.
