I have no problem starting projects! Finishing them is what gives me the trouble!
There is always something else I want to build, and if I let that get the better of me, I find myself spread to thin, never getting any one thing completed. It used to be really bad, but I'm slowly getting better. These days I'm trying to stick to one project, before starting another, but I am still buying parts for the 'next project'. Eventually I'll get a truck done! Then I can start on the next big thing.
