For example does thinking my life is improved seconds after affirming and finishing a square affects the working?
Discussion
Ideally you should do your visualizations alongside the affirmations during the working before you end it for the day.
Yes, infusing the working with a powerful emotion will have an effect, but this should ideally be done during the affirmation phase. Try and utilise a strong conviction and/or emotion alongside the relevant visualisation(s) in order to make the internal experience feel as "real" as possible to the subconscious.
