Hi redplant
In order to start you've to do nothing special (i.e. No signing contracts with blood or selling your soul, haha). You can stop watching P and MOing today at this instant. You can keep a journal here where you can write up your daily experiences or improvements after giving up PMO. Also, you can get a counter to help you motivate in this journey. However, if you're really serious about this, you can join a group called Heirs of the Sun. This is a small group which is dedicated in defeating the PMO addiction. They run a tight ship, and someone is always available for help. So, if you're interested, give it a shot.
