Whatever work you do, you may experience that feeling of being overwhelmed, tired, or in need of inspiration and connection. If you can spare 15 minutes in the "no time for anything" zone, replenishing your body and brain with oxygen and chi can do wonders for you - and, therefore, for all those you come in contact with. You don't even need a mat, just a chair will do (just make sure it's stable). I sometimes do this practice in hotel rooms, or even convention centres.
