What's one thing these people can take right now to help them?
Reading positive mindset book, books that elevate your mindset in the world of possibility. It's creating microburst of neuroplasticity. When I'm learning, anytime I'm learning something new, it's creating some neuroplasticity. Meditation is great, and there's a lot of 5-minute guided meditations. I've got my Claim Your Power NLP meditation if you want to reprogram subconsciously some things while you do the meditation. That's free, just on YouTube. And the third thing, breathwork actually really works because it move stuff through your nervous system. Exercise actually helps too.
