Practice Meditation
Meditation is a great way to cleanse your mind. Mindfulness will help you achieve your goals.
Begin with sitting in a quiet place, closing your eyes, and counting till 38. It might seem troublesome at first because your mind keeps wandering, and it is easy to get distracted. If so, then start afresh without any sense of self-judgment.
Take it slow, and you’ll learn the way to calmness.
