Awesome article. I use to wake up early before but couldn’t continue due to my new born :). Now, he is one plus and I have started waking up at 6am now. I feel a huge difference. I feel more control on my work, I am happier. I am going to gradually wake up by 5.
For someone, who wants to starts waking up early an advice - don’t think from tomorrow you will be able to do. Do it gradually and slowly in a tapered way. 10 minutes early from your current time of waking up. Cold turkey won’t work for most of us.
