Necessity. Ask yourself, do I absolutely must practice organ playing? Would I miss organ playing, if I wasn't allowed to practice? If the answer is yes, go on to the next point.
Choice. Understand that changing your attitude towards organ is a choice. You can keep playing the way you are used to and get the same results or you can make change happen.
Goals. If you really want to change and get out of the circle, you need to set short-term and long term goals. Where exactly you want to be as an organist in 1 month, 3 months, 6 months, 1 year, 3 years, 5 years or 10 years from now?
Obstacles. What are the challenges you must overcome on your way of achieving these goals? Pick at least 3 for starters.
Action. Stop wishing, dreaming and take action. Today. And tomorrow. And the day after that.
All of the above happens in your mind. Change your mind and you win.
