Do-it-yourself, home-based & absolutely free yoga

Early this morning, all of a sudden, I felt the urge to just sit on my bed facing the sunshine, be content for a moment, not think about the cases and exams, and enjoy the bright sunlight coming through my window with a smile. I am not an early-morning person, and I definitely do not wake up by myself when it's light or when it's noisy (I can sleep through anything hehe). But for that moment, I realized: "This is why people love waking up early, to see the sun smiling at you."
