Regret

There are four things you cannot recover:

the stone after the throw,
the word after it is said,
the occasion after the loss,
the time after its gone.

I read this in one of newly favored Indonesian columnist, Samuel Mulia. He quoted his friend in his weekly column of Kompas Daily. Read on from here.

So true, we might regret what we throw, words which we've said, occasion which we've loss and the time after it's gone.

We might regret for not doing things differently, might regret for saying the words or even regret for NOT saying it.

I am in constant learning for not regretting anything.
Everything must have it's purpose in our journey.
