Self help tapes, psychologist, motivation course, and lots of ginseng and caffeine.
I alternate between Alpha frequencies and Beta frequencies. I use a different one every hour, averaging about 6 to 7 programs a day. I also use it religiously when I surf the net at night. It works with all the database, word processing, and spreadsheet programs I use at work. I'm in front of the computer, which is a lot.
