Do you end every day feeling guilty and ashamed because you haven't done enough? It wouldn't have killed you to send just one more email, or spend just 30 more minutes on your writing, right? Well, sure, you could go flat out. But you wouldn't last long if you did. You need to pace yourself, which means you definitely shouldn't be dialling the effort up to 11 on a daily basis. Your mistake is expecting yourself to sprint for the whole marathon - and that's just bonkers. Crack out the headphones and let your imperfect friend here talk some sense into you.
