You’ve probably heard of mindfulness, but may not know much about it. Mindfulness is a type of meditation practice based on Buddhist meditative traditions from over 2,500 years ago. It is the practice of being aware of what is happening in the present moment. Author Walpola Rahula wrote that “[Mindfulness] is simply observing, watching, examining. You are not a judge but a scientist”. 
Why you feel Unhappy
The major sense of dissatisfaction you feel today comes from a focus on a future state or from dwelling on the past. In essence, your lack of presence causes unnecessary suffering by either reliving past insults or worrying about an unknown future outcome. This creates a profound tension in the nervous system, which eventually saps you of your energy.
How Mindfulness can Help
First, observing your present state is grounding and calming. Not only will you be present, but you will do a better job at what you are doing. Your task becomes your meditation and your meditation becomes your task. Second, you begin to accumulate both the skill of being present and the ability to accomplish the things you have identified as important. Finally, you will feel more calm in your daily life and be better equipped to handle the daily challenges that come your way.
