Mindfulness is our greatest treasure, but I recently received advice from a wise friend on a method that can help us maintain mindfulness during most any activity. Usually if we're not really thinking about it, we forget that we are a process (aggregates undergoing constant change), and perceive ourselves as a static "thing".
One useful thing to do is to train your mind to remain aware of your breath, no matter what you are doing. Being aware of the breath helps you remain aware that you are a process; this breath is life, without it the process ends and so do you.
It's pretty simple, but it has a subtle and profound effect. It comes fairly naturally to me because my preferred method of meditation is observance of the breath, but I don't think it would be difficult for you. Depending on you, it might also make activities you dislike seem less distasteful. The reason for this is that in remaining aware of the breath, that you are a process and not a static phenomena, you are distancing yourself from your "self".
The "self", which is a construct of the mind, is non-self. It is not us, and we are not it. This self blinds us to reality; it is our Mara, our Satan, our Hades. Cast it out and behold the path to freedom.
