Now, don't think that if you don't have time to practice 6 hours a day, you can't achieve anything worthwhile in organ playing.
If you can practice for 15 minutes 6 days a week (most people even with the busiest schedules can) - that's 90 minutes per week.
That's 6 hours a month. That's about 75 hours a year.
That's enough for one hour recital of completely new music.
