I did this for several months while I was taking the Stanford AI class. I got up at 6, did coursework for two hours or so, and went to work by 9.

I found it to be highly beneficial for several reasons (some of which were mentioned in the blog post): -since I am usually exhausted by the end of the day, I found the early time to be really conducive to clear thinking -early part of the day is so quiet-- no interruptions -I felt like I accomplished quite a bit even before arriving at work, so I somehow felt more productive even though I should have been more tired

I intentionally did not keep up the early time on the weekends and slept in-- btw, 8am felt like sleeping in :)

Since the class finished, I kept up the habit and wake up early to code or read.

I admit it isn't for everyone, but it is worth a try for anyone who wants to code after work but feels too tired or easily distracted.
