On a train to work I wrote 910 words for a new Quora answer.
I added 220 more words to it, spellchecked, formatted and published it.
I took an od Quora answer and published it on my blog. It took some formatting though.
On a train back home I replied to a few emails from my readers achieving Inbox Zero.
I sent the emails and show my sons how to mine for keywords on Amazon and how to make keywords inventory from existing ad campaigns.
I slept over 6.5 hours.
