Methods of increasing mindfulness, raw observation

Please share methods to increase mindfulness. \ Mindfulness means simply an awareness of the objects and sense data that are present. So, for example, it is Tuesday, 1pm. What I have tried so far is to list things and sights that are nearby: - Is it light or dark? - Am I tired or not tired? - Am I walking or sitting? Is it simply raw observation, independent of cast or creed, simply seeing as it is? Thanks sukhi hontu
