Just going straight into 15 minutes loops can easily lead to stonewalling which IMO is often worse than “normal” recon, as nothing moves at all anymore for a while.
Starting with micro loops and very slowly increasing is good and recommended.
Regarding recon: In my experience one factor a bit underdiscussed is how/if you expect recon. As with many aspects subliminal recon can give a lot of projection space for FUD. If I sit alone at home, listen to a sub and waiting for recon to hit, “recon” will hit. (probably with a good bit of autosuggestion)
To change my attitude towards recon/subs in the beginning it helped me to listen to my favourite music, watch ARCHER (my TV happy place) or enjoy a lovely choco tartelette while listening to it. Scent often helps too.
Even better’s listening to a sub and going straight into action taking. (e. g. listening to a social sub and heading straight to a party with friends.) And not thinking about the sub at all, but concentrating on the (party) action.
