Quitting

Yesterday I listened to a replay of an old Freakonomics podcast entitled The Upside of Quitting, which discussed the positive aspect of quitting something that wasn't going to have positive outcome. It got me thinking about myself and how I tend to have an irrational tenacity about staying with things.
My problem with quitting usually stems from the fact that I never feel like I truly gave it my all that if I would push a little harder the situation would turn out positive. The fact that I rarely feel I have given something everything I have prevents me from quitting something with a clear conscience.
This brings me to another point I have mentioned previously, that is having your basics in order, meaning you are trying your best at whatever you are doing today. Now there may be a constraints preventing you from doing your best but you are trying with at least the resources you have.
The main reason for this post is that I have decided to quit a project (for the time being at least) and that is my Grouper project. It was a to be a web app that would be used to organize small groups, for example book clubs, sport teams etc. I have worked on it dutifully for the the last 9 months but it is still far from a state of completion and it will take a lot more study and effort to get it there. So I have decided to quit and leave it.
I may start it back up if the following items are accomplished

1. I find a dream job making $30,000+ than I do now.
2. My finances are in order
3. Shelby is doing well in her math.

The above are pretty arbitrary but will serve for now. And maybe I can start it back up in a month or so with new vigor and understanding.
