I am notorious at getting started on one project only to be side tracked by another. I am usually doing three projects at once, much to the annoyance of Pam though she never says anything it's just the way she talks and the facial expressions that scream hurry up.
They all get finished. Sometimes however I start one project as it needs a new tool to finish. This is so I can say to Pam I can't finish it unless I have a new plane and I don't have one. hopefully the answer is "well I guess we will have to get one".
Sometimes it works!
