Sometimes you just do a project 'cause you want to.
It may or may not make any financial sense but some of us just enjoy doing that sort of thing.
Others spend hours on the golf course, out on their boat, any number of different activitys. None re-pay in anything other than satisfaction.
That's all we look for in some of these.
Then there are the projects some of us do for the above reason plus they do make financial sense.
We do all or most all the work ourselves.
We're working on something we decided to do, not a 'job' picked out by someone else. Very enjoyable that way.
When finished, there's a nice custom or restored piece to play with for a while and then perhaps sell,,maybe play with a bit longer before selling.
Then do another project,,there's just so many around.
