James:
Welcome! Like others here, I've had a similar experience to yours. You begin to learn that the Society demands total loyalty. But their only loyalty to you depends on whatever you are currently doing. Past efforts mean nothing.
Learn to brush off attempts to guilt trip you. And don't offer any explanations why you don't do whatever they want, such as occasional pioneering. My suggestion for a next step: Kick the TMS to the curb; 'retire' from it. And give no reason. They don't deserve any.
