'Mindfulness' has become a bit of a jargon term! Don't let that deter you from experiencing its benefits.
Mindfulness techniques allow you to reduce stress, anxiety, and depression.
Practicing mindfulness teaches you how to make your brain's flight/flight/paralysis mechanism less reactive.
You will gain clarity and insight, and learn to tame the clutter and racing thoughts that give you little peace.
You will experience self-awareness and gain a sense of control. You will be able to choose how you responde to stressful situations rather than reacting to them. You will discover what it is like to be relaxed, gain self-acceptance and self-confidence.
