Habits are what we can repeatedly do.
That makes habits the same as processes.
As a process, the steps of a habit can be documented.
As a process, the process can be re-engineered to be more efficient
As a process, there is a supporting context for the process
As a process, metrics can be collected to quantify the process and any improvements
As a process, learning from other processes apply
Treat your habits as you would treat any type of business process.
