Any workout which does not involve a certain minimum of danger or responsibility does not improve the body - it just wears it out.
Norman MailerThe novelist ... must live in paranoia and seek to be one with the world; he must be terrified of experience and hungry for it; he must think himself nothing and believe he is superior to all.
Norman MailerThe writer can grow as a person or he can shrink. ... His curiosity, his reaction to life must not diminish. The fatal thing is to shrink, to be interested in less, sympathetic to less, desiccating to the point where life itself loses its flavor, and oneโs passion for human understanding changes to weariness and distaste.
