After I commented on this I had to go to supermart for some medicine and I thought about using this technique. I'm already too much fluent but I always get trouble when saying medicine names, city names aur words which start with Q, K. I switched from FPP to TTP and it worked but this technique requires alot of effort, imagination and mental strength. I did what you said but can't do at your level. I think like I'm in a movie but only focused on by back. I will put more effort on it and if my Q, K words and some block got overcome with this technique then I will be 100% fluent. Btw thanks for this technique and share if you had something more under your sleeves
