It would appear that it's quite easy to fall off the wagon even after doing something consistently for 30 days.
I had a friend ask me for some advice about setting their own blog up because I was suddenly "blogging my brains out". It made me smile and tell him about Cricket's 30 Day challenge where I have to blog every day for 30 days. Now he probably thinks I'm crazy (if he didn't already). But it also made me think about how I nearly threw it all in earlier this week.
