Waking up early for a passion/dream/business is different to HSC. I wouldn't mind waking up that early if I'm trying to achieve something of my dreams. For the HSC, not so much haha..I agree and all, however, many successful businessmen / or people (for those wanting to be politically correct) generally wake up at 4 to 5 in the morning and workout, meditate and work. This is as you have no distractions around you and most of your social media, emails and texts won't occur as everyone else is alseep. However, if you decide to follow this, you must regulate your sleep and exercise in the morning to keep you boosted. When doing this, I found that I was more alert, as you have been up for longer.
