Everybody Can Change
Transactional analysis is based on some philosophical assumptions about man, life and the objectives of change.
Every individual is ok
This is summarized in the expression: "I am ok, you are ok".
The person, as such, is endowed with value and dignity and deserves acceptance and respect. No one can be considered superior to another: people are equal to each other and each has value regardless of their race, age, religion and socio-cultural background. What may be debatable is the behavior (what you do) not the essence of the person (what you are).
Everyone is capable of thinking and therefore decides what to do with his/her life.
It is everyone's responsibility to decide what they want in their lives; everyone is responsible for their own decisions and their consequences. If with some decisions it gets negative results it has the power to change them.
The therapist-client relationship is based on a collaborative contract towards a common goal. There are specific competences and responsibilities: the client is the only one who has the responsibility and the power to concretely act out change, the therapist has the responsibility to make the most of his/her specialist skills and his/her human talents to stimulate and support the client.
