Take this at least, this last advice, my son:
Keep a stiff rein, and move but gently on:
The coursers of themselves will run too fast,
Your art must be to moderate their haste.
Cunning leads to knavery. It is but a step from one to the other, and that very slippery. Only lying makes the difference; add that to cunning, and it is knavery.
Beneath the sun's rays our shadow is our comrade;
When clouds obscure the sun our shadow flees.
So Fortune's smiles the fickle crowd pursues,
But swift is gone whenever she veils her face.
There is nothing in the whole world which abides. All things are in a state of ebb and flow, and every shadow passes away. Even time itself, like a river, is constantly gliding away .
