Sarah Eika Burke, a mother of two and personal trainer and Start TODAY app trainer, has found that making lists can help her stay organized and keep mentally motivated throughout her busy schedule. She shares her most important daily habit: crossing things off her lists, a physical gesture that gives her a sense of self-validating. The benefits of lists include helping to get multiple tasks done in succession and helping to reduce stress, which has been linked to depression and anxiety, heart disease, poor sleep, weight gain, and more. Eika uses lists as a tool to set boundaries, put her phone down and be present.
