Yeah, sometimes I miss a step too. I'll buy a thing and not put it up, or forget to work on something. It's why my goals page has a list of many things, so I remember to do them.

One thing that helps with getting started: make it small enough that you can start it immediately. Drabble, vignette, haiku -- we even have an Achievement for Diamonds & Dynamite. You can make a 2x2 or 3x3 card too.
