“For no man is free who is a slave to his body."

“Putting things off is the biggest waste of life: it snatches away each day as it comes, and denies us the present by promising the future. The greatest obstacle to living is expectancy, which hangs upon tomorrow and loses today. You are arranging what lies in Fortune’s control, and abandoning what lies in yours. What are you looking at? To what goal are you straining? The whole future lies in uncertainty: live immediately.”

"You become what you give your attention to."

"Think of yourself as dead. You have lived your life. Now take what's left and live it properly."

“Each of us lives only now, this brief instant. The rest has been lived already, or is impossible to see.” 

"At dawn, when you have trouble getting out of bed, tell yourself; ‘I have to go to work, as a human being. What do I have to complain about, if I’m going to do what I was born for — the things I was brought into this world to do? Or is this what I was created for? To huddle under the blankets and stay warm?—but it’s nicer here? So you were born to feel ‘nice’? Instead of doing things and experiencing them?"
