The following extracts are taken from Seneca's Letter Thirteen in "Letters from a Stoic" and stand for themselves. This content is taken from an article on The Marginalian (formerly Brain Pickings) Website. Since I am afraid to fail and consequently end up procrastinating (which I can ill afford), I needed to be reminded of what is laid out below.
"There are more things […] likely to frighten us than there are to crush us; we suffer more often in imagination than in reality.
"[…] What I advise you to do is, not to be unhappy before the crisis comes; since it may be that the dangers before which you paled as if they were threatening you, will never come upon you; they certainly have not yet come."
"[…] It is likely that some troubles will befall us; but it is not a present fact. How often has the unexpected happened?! How often has the expected never come to pass?! And even though it is ordained to be, what does it avail to run out to meet your suffering? You will suffer soon enough, when it arrives; so look forward meanwhile to better things. What shall you gain by doing this? Time. There will be many happenings meanwhile which will serve to postpone, or end, or pass on to another person, the trials which are near or even in your very presence. A fire has opened the way to flight. Men have been let down softly by a catastrophe. Sometimes the sword has been checked even at the victim’s throat. Men have survived their own executioners. Even bad fortune is fickle. Perhaps it will come, perhaps not; in the meantime it is not. So look forward to better things.
"[…] The mind at times fashions for itself false shapes of evil when there are no signs that point to any evil; it twists into the worst construction some word of doubtful meaning; or it fancies some personal grudge to be more serious than it really is, considering not how angry the enemy is, but to what lengths he may go if he is angry. But life is not worth living, and there is no limit to our sorrows, if we indulge our fears to the greatest possible extent; in this matter, let prudence help you, and contemn with a resolute spirit even when it is in plain sight. If you cannot do this, counter one weakness with another, and temper your fear with hope. There is nothing so certain among these objects of fear that it is not more certain still that things we dread sink into nothing and that things we hope for mock us. Accordingly, weigh carefully your hopes as well as your fears, and whenever all the elements are in doubt, decide in your own favour; believe what you prefer. And if fear wins a majority of the votes, incline in the other direction anyhow, and cease to harass your soul, reflecting continually that most mortals, even when no troubles are actually at hand or are certainly to be expected in the future, become excited and disquieted.
