Because we are more dependent on ourselves as individuals, you can spend the time with yourself with optimizing yourself. Think of development: enrich yourself with online art in museums all over the world, deepen your knowledge in music, take a virtual journey by Googling cultural topics and visually bring the world into your home while sitting on your own sofa.
Also think of optimizing your health, your own body. By studying nutrition you will find out which hand you have in managing your health. You will find that the more you learn, the more fun it gets. Knowledge is fun. If you also adjust your behavior in terms of eating, you will come a long way. Eat your meal carefully: chew and taste instead of bite and swallow.
