When you elevate the heels more so than you elevate the sole of the foot, you trigger a cascade of compensations in the knees and hips that cause tight hip flexors, and then those hip flexors cause lower-back pain.
Tim FerrissI do my best writing between 10 p.m. and 5 a.m.. Almost every friend I have who is a consistently productive writer, does their best writing between 10 p.m. and 8 a.m. My quota is two crappy pages per day. I keep it really low so I'm not so intimidated that I never get started. I will do the gathering of interviews and research throughout the day. I'll get all my notes and materials together and then I'll do the synthesis between 10 p.m. to bed, which is usually 4 or 5 a.m.
