American health and fitness guru, Jack Lalanne, who passed away at the age of 96, used to say that “you have to know how to satisfy yourself, and those who don’t, will fail at life.” The satisfaction Jack spoke about referred to many things – from physical exercise and nutrition to rest and leisure. Remember, it’s important to love and respect others, but if you want to live to 100, don’t neglect the most important person in the world – you.
