Transactional is suitable for self analysis and application of its concepts to yourself. It therefore makes sense that you aren’t necessarily dependant on a therapist; that in fact you can make a contract with yourself and monitor progress yourself. It would be best to have some independent source to confirm the contract and we would suggest you write it down.
The influence of upbringing/education when rejecting the rules
A child taught that rules are constraints against their natural urges will rebel against rules as undue violations of their freedom. Children who learn that tantrums make rules bend will challenge them passive-aggressively or aggressively until they get their way or face a serious consequence.
Influence of upbringing/education when tolerating the rules
Rules can be accepted as necessary for someone’s safety. Boundaries can even be a sign of love and concern, such as parents strictly enforcing a “don’t touch the stove” rule. The parents care enough to create rules for the child’s safety and then enforce it, allowing children to know that everything that is permitted is safe.
