Read the letter of Epicurus which appears on this matter; it is addressed to Idomeneus. The writer asks him to hasten as fast as he can, and beat a retreat before some stronger influence comes between and takes from him the liberty to withdraw. But he also adds that one should attempt nothing except at the time when it can be attempted suitably and seasonably. Then, when the long-sought occasion comes, let him be up and doing. Epicurus forbids us to doze when we are meditating escape; he bids us hope for a safe release from even the hardest trials, provided that we are not in too great a hurry before the time, nor too dilatory when the time arrives. …

Now is the time for me to pay my debt. I can give you a saying of your friend Epicurus and thus clear this letter of its obligation. “It is bothersome always to be beginning life.” Or another, which will perhaps express the meaning better: “They live ill who are always beginning to live.” You are right in asking why; the saying certainly stands in need of a commentary. It is because the life of such persons is always incomplete. But a man cannot stand prepared for the approach of death if he has just begun to live. We must make it our aim already to have lived long enough. No one deems that he has done so, if he is just on the point of planning his life. You need not think that there are few of this kind; practically everyone is of such a stamp. Some men, indeed, only begin to live when it is time for them to leave off living. And if this seems surprising to you, I shall add that which will surprise you still more: Some men have left off living before they have begun.

As Seneca recorded: Sic fac omnia tamquam spectet Epicurus! So do all things as though watching were Epicurus!
And as Philodemus wrote: “I will be faithful to Epicurus, according to whom it has been my choice to live.“
