Ok, so the three things a week thing didn't work out so well last week. I got two in one day, though. That sort of counts.
When you start something like this it's easy to keep going. You tell a few friends, get some positive feedback, generally feel good. The excitement just keeps you going. Then after a while you start to notice nobody seems to be paying any attention. That's no fun and kind of takes the wind out of your sails.
That's where the hard part starts - keeping going.
