How far in advance do you plan the monthly topics and when do you announce them?

I feel I am not your typical member. I am 68 and retired. I joined for your relationship month of May but I am not sure the future topics will fill any need in my life. Because we have to give you 30 days notice to cancel I feel like we are being asked to stay when we don’t know what the next month’s topic is. I know you want us to stay for a year but I am sure you don’t want us to buy something that we really don’t want or need.
