Have you had the experience of enjoying you own companion? You alone with yourself? The fact of being alone scares some people. They just want to be around somebody. They don't like the feeling of loneliness. They rely on external factors for being alive and entertained.
On the other hand, some people enjoy being alone. They accomplish more when alone. They feel more alive and self-content when alone. Why does this happen?
When we appreciate every moment of our life, we do our best every moment of it no matter what the circumstances is. We accept the moment as it comes and try to benefit from it in every way we can. Keep on flowing like water to maintain our purity. Stagnant water collects dirt, so flow with the moment smoothly and gently, just like a flowing water.
I had this experience before; being alone. I had a list of tasks to do. So I do each one mindfully, enjoying myself. My focus were sharp on the moment at hand. I completed the task smoothly and was feeling much more efficient and happy.
From my observation, to live mindfully, you have to focus on your moment. Whatever you are doing or feeling, make it special. Let other things freeze. Only the doing or the feeling is happening and you are enjoying it. Time doesn't stop or pause, so should you. Just flow with the moment.
