@Kumar Aryan As David said, I'd highly recommend "Why We Sleep" by Matthew Walker. It's an exceptional book and changed my life in how I view (and utilize) sleep. Regarding all of your current pressures and challenges, it feels counterproductive to "waste time" sleeping when you have everything else going on. But if you invest 7-9 hours in sleep, it will pay countless dividends towards actually mitigating or solving most of those challenges your facing (focus, procrastination, fatigue, relationships, etc.). I'd also recommend checking out Pareto's principle on time management. Tasks demand every second we grant, so block sleep time and protect it from the busy work.
