Mindfulness means paying attention to where you are and what you are doing at any moment without feeling overwhelmed. It is being present and fully aware of your experiences without overanalyzing the current situation.
The most common way to practice mindfulness is through meditation. Start by sitting still and inhale and exhale through your nostrils or mouth while focusing on the feeling of your chest or belly rising and falling. After you have mastered focus of your chest or belly moving, broaden your scope and slowly introduce focus to other things such as sounds, smells and thoughts.
Another way to practice mindfulness is through single-tasking. Choose to do one activity at a time so that you can give it all of your focus with zero distractions. Mindfulness can also be done through journal writing.
Mindfulness works because it brings your thoughts and feelings to the forefront of your brain and allows you to focus on one thing at a time and fully explore it before moving on.
