TM and its advanced programs. Twice a day. Part of my life. It might need a letting go of less important activities in order to be reschedule one's daily life and be regular, but it's worth it. And having regular times each day (if possible) helps to culture the new routine. That helps educate family members too, that this is the time you don't get disturbed. Of course, flexibility also plays a part, seeing we live in a society and often in a family situation. But I believe regular is best, with occasional exceptions as necessary.
