I really like the Scientology Handbook site.

There are selections from many of the chapters, and these contain very helpful tips and technology for doing better in life.

There's a chapter on Targets and Goals, for example, which is very simple but brilliant.

L. Ron Hubbard developed what he called an Administrative Scale, which you can use to sort out a job, a business, a city, a country, your own life -- you name it.

This is one I highly recommend.

I also suggest anyone interested in gaining some ability in handling their lives get a copy of the book (which is much more extensive that the selections that are online, as good as those are).
