最大的荣耀不在于永不跌倒，而在于每次跌倒后都能站起来。
The greatest glory is not in never falling, but in rising every time we fall.
Memory is the only paradise from which we cannot be driven.
In all affairs， it's a healthy thing now and then to hang a question mark on the things you have long taken for granted.
"Books are like a mirror. If an ass looks in, you can't expect an angel to look out."
