How to consistently sustain an elevated emotion?

I’ve been practising the Tuning Into New Potentials mediation for quite some time now, which aligns with my current goals.

However, most of the time, I fail to sustain an elevated emotion attached to my clear intention. I just keep on falling back to what’s going wrong currently, and I know that’s moving to a place of lack.

How do you sustain that elevated emotion? How do you start it and maintain it throughout your mediation, and possibly even in your daily life?
