Pay attention to your chi. If you sense it is lagging, you need to give it a boost. This can be done many ways. For those who prefer physical activity, exercise is a great way to get the good chi flowing again. For the less active, just making a hot cup of tea in total mindfulness can help. Experiment and find what works for you, activity or rest. There are many things that can disrupt the good flow into a choppy or blocked one. Knowing how to revive it is most important.
