Engage in meditation this week – there are many types of meditation which people practice. Simply closing your eyes and focusing on the pattern of your breathing, listening to your heartbeat, and visualizing the stress melting out of your body, is an easy pick-me-up which can be done nearly anywhere. You can find guided meditations online; you can practice walking mediation or other physical motion meditation (anything physically repetitive that lets your mind simply be present in the moment works really well for this), you can sit and visualize a flame (or have an actual candle) and let all your thoughts come and go. If you do not find one sort to be your cup of tea, experiment with another one.
