I'm not a mathematician, so I apologise in advance if my question expressed ignorance. I want to have an equation for the notion of perpetual deferral. My example is of someone who is addicted to smoking [or wants to go on a diet] and their modus operandi is ‘I’ll quit tomorrow’…‘this is the last time’ etc. So I need some way of expressing this. i.e. Addiction = ‘the last time’ + 1…ad infinitum [1 being an additional ‘last time’] If anyone who understands this stuff a little better than myself I would very much appreciate your assistance.
