No you can’t, fake creates fake
It’s better to stay feeling good about something even if it seems like it’s got nothing to do with your goal. Everything you want feels good and is already sitting in the place where you feel good. If you want a real experience then imagining it or talking about it must feel real.
People who’ve suggested doing this have only recommended this because they didn’t fully realise it was not the imagining that created it, it was because of the passion they were feeling.
