Seneca

"He who fears death will never do anything worthy of a living man"

"A gem cannot be polished without friction, nor a man perfected without trials"

"The whole future lies in uncertainty: live immediately"

"As is a tale, so is life: not how long it is, but how good it is, is what matters"

"No man was ever wise by chance"

"Difficulties strengthen the mind, as labor does the body"

"He who is brave is free"

"It is not that we have a short time to live, but that we waste a great deal of it"

"Luck is what happens when preparation meets opportunity"

"We suffer more often in imagination than in reality"
