It is our biological nature to also form good and healthy habit patterns. We can teach ourselves to exercise in the morning, eat smaller portions of food, finish a book before starting another, and to not spend our money impulsively. The capacity to form good habits also extends to our thinking. We can train ourselves to say "Too bad" instead of disturbing ourselves when important matters do not go as we want them to go. We can train ourselves to accept what we cannot change.
We I was in training with Dr. Albert Ellis he would so often say "Repetition is the mother of learning." I can still hear him saying "work and practice, work and practice is what is required to change and you should run from anyone who attempts to fool you into thinking you can achieve positive change through insight alone and change in an effortless manner."
People sometimes try to argue that there has to be more to therapeutic change than effort, repetition, reflection on one's performance, and then repeating the entire sequence again. Perhaps there is a bit more but certainly these are the essential ingredients of therapeutic change.
Patients will ask "I see the logic of unconditional self-acceptance but how do I come to adopt that attitude towards myself and only rate what I do to determine if what I have done is successful in achieving my goal?" I answer that you need to repeatedly think about the truthfulness of unconditional self-acceptance and how it is invalid to rate a human being as a human, you need to think about how the concept is useful in helping you stay with changing self-defeating behaviors, you need to recognize that since you have repeatedly thought in a conditional way about your worth for many years you will have to repeatedly practice thinking differently about yourself to unlearn your conditional self-acceptance." I close by saying “You have to act in a way consistent with unconditional self-acceptance to truly internalize this very useful concept”.
REBT offers good and very sensible solutions for fallible humans. You can learn new and healthy habits of thought and action. However, this self-training takes work and practice, work and practice. Why not start right now on a new habit that will help you do better in life and become less disturbable?
