That may have been me.
Its available on amazon.
By WILLIAM glassser.
Its a very useful book and is a basis for learning to take control of yourself and accept that you cannot control another,.
For co-dependants it just fantastic.
It puts you in control of your own life and behaviour.
Easy to read.
The theory is based on this premise
If you are miserable you have 3 choices
Change what you do
Change what you want
7 habits is the best book ever but you need to be areader but its the best
thought for all of us choice theory is bang on
Be prepared to resist the theory it really asks you to be totally self responsible
