I have an aversion to starting anything. I have to force myself to start. Most times, once I start, I am good for the long haul.
Sometimes, when I want to do something & I am procrastinating, (probably 'glued' to the computer) I tell myself that I'll just do it for 5 minutes. Over 90% of the time, I will get in the groove & continue with the project.
It works for me.
Now...I must go move the dust around for 5 minutes!
