There are many mindfulness practices that you can try that will help you focus your mind on the immediate present and disconnect from worries, regrets, and anxieties. The type of practice that best helps you will likely be individual to you. But here's a beginner's mindfulness practice you can try. (1) Wherever you are, close your eyes and breathe deeply. (2) Focus on your breath. When you feel your thoughts begin to wander, bring your mind back to the breath. Many who try a practice like this mention that they soon learn to notice their thoughts as separate from themselves, which eases anxiety and helps them stay calmer throughout the day.
