the greatest waste of life lies in postponement: it robs us of each day, and snatches away the present by promising the future. The greatest impediment to living is expectancy which relies on tomorrow and wastes today
Two elements must therefore be rooted out once for all, – the fear of future suffering, and the recollection of past suffering; since the latter no longer concerns me, and the former concerns me not yet. – Seneca
“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.” - Marcus Aurelius
“I cannot boast that I waste nothing, but I can at least tell you what I am wasting, and the cause and manner of the loss; I can give you the reasons why I am a poor man.” -Seneca
“I judge you unfortunate because you have never lived through misfortune. You have passed through life without an opponent—no one can ever know what you are capable of, not even you.” – Seneca
If you are pained by any external thing, it is not this thing that disturbs you, but your own judgment about it. And it is in your power to wipe out this judgment now. - Marcus Aurelius, Meditations
