If you have a test tomorrow, but try to live in the present you should still study. Living in the present is not just living for the present. Thoughts about the past and the future are thoughts of the present. If you are at a place in your life where you are fully engaged in the present, then you will do what you need to create a peaceful present that passes into a peaceful future and leaves a peaceful past. Passing exams and engaging in learning can help create a peaceful present, past and future. Tomorrow’s test is part of your present. Be present as you study.
