1. I need to be a clot over the wound that which heals …Not a clot in the artery that clogs.
Nihara
2. This is the true joy of life: the being used up for a purpose recognized by yourself as a mighty one; being a force of nature instead of a feverish, selfish, little clot of ailments and grievances, complaining that the world will not devote itself to making you happy.
George Bernard Shaw
3. When the juices of trees have no means of escape, they clot and rot in them, making the trees hollow and good for nothing.
Marcus Vitruvius Pollio
