“Pause you who read this, and think for a moment of the long chain of iron or gold, of thorns or flowers, that would never have bound you, but for the formation of the first link on one memorable day.”
– Charles Dickens, Great Expectations
Everything has a start and an end. If something we did started it, it is definitely within our power to end it (again, by doing something towards it).
If things don’t turn out to be as we would have liked them to be, we can always do something about them to change their course… Why lose hope?
