How can I start mindfulness reliably with a busy schedule when thoughts race?

[Hannah88]

I've been trying to establish a consistent mindfulness practice to manage work-related anxiety, but I find my mind racing even during guided meditations, and I often end up more frustrated than calm. I've tried a few popular apps for short sessions in the morning, but I struggle to see any lasting impact on my daily stress levels. For those who have successfully integrated mindfulness into a busy schedule, what specific techniques or types of practice did you find most accessible at the beginning? How do you handle the inevitable distractions and self-judgment during a session, and did you find it more helpful to focus on breath, body scans, or a different anchor? I'm also curious about how long it took before you noticed a tangible difference in your reactivity.
