A story: When Socrates met his teacher

There's a saying in Malay:

" Kesal dahulu, jangan kesal kemudian"

It means: " Regret beforehand, don't regret afterwards."

During his younger days, Socrates visited a brothel and as he was coming out of it, he saw his teacher passing by. The young man was embarrassed and tried to sneak away, but the teacher accosted him and asked why he was trying to avoid him.

Socrates replied that he was ashamed of what he had done. His teacher advised, " You should have been ashamed of your actions before you entered the house of ill repute. Then you would have avoided doing the deed which you are now ashamed of."

Vice is easily learnt without a master,

whereas virtue requires a tutor.

Good habits are difficult to acquire

but easy to live with.

Bad habits are easy to acquire

but difficult to live with.

~ Ven.Dr.K.Sri Dhammananda

Its easy to splash a bucket of paint on the wall mindlessly; 

But it takes a lot of effort to clean the mess off the wall.
