you can’t make naiveté happen, you can only allow yourself to be more naïve, in this moment – it is something outside the domain of the ‘controller’. It happens when you allow life to happen, not have it ‘your’ way. Hence a good way to start is to put everything on a preference basis, give up control a little – and don’t expect everything to happen at once (like a big leap to “the state of ‘gay abandon’”) – that again would be the opposite of being naïve.
You can experiment when doing nothing in particular for a while, and not know what is going to happen next, feeling a bit foolish perhaps, that’s ok, then a bit more of that, allow the objections and recognize the silliness, then get back to feeling good. Just explore what happens without plans how it should turn out …
