Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.
If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it; and this you have the power to revoke at any moment.
It is not death that a man should fear, but he should fear never beginning to live.
Be content with what you are, and wish not change; nor dread your last day, nor long for it.
