Also, this is the least useful comment by pg i've seen in a long while. It's not even funny if you happen to be a late sleeper.
The are both very useful and correct answers to the OP. I don't think it needs to be funny. Its simply correct. Most of us have far too much to do every day and end up working too late. If you want to wake up earlier, you have to stop doing that.
I'll leave with this one (also not meant to be funny):
"Early to bed, early to rise, makes a man healthy, wealthy, and wise."
Somewhat off topic, you realize it's a real disservice to pg to upvote and defend any comment he makes indiscriminately? Or even with less discretion then normal.
