What about using goals as MVP's for frameworks/systems?

For instance I recently decided to read an academic paper every week. It is posed as a challenge, but if the results are good I will simply continue reading an academic paper every week and voila, a system.

I've used a similar approach for pretty much every good habit I keep. Start with a goal, then just don't stop. This has worked for everything from working out 3 times a day, to writing and programming.

Start with a goal, end up with a system.
