Consider a pet
You have the opportunity now that you are not concerned about a roommate's allergies or a sibling's fear of dogs. You'll never return home to an empty house if you have a pet.
Additionally, as evidenced by the countless pet videos on YouTube, pets give both entertainment and physical comfort (stroking a dog can release hormones that improve mood). Because pets require regular feeding and attention, owning one makes it simpler to stick to a schedule. A dog will make sure you go on a couple of daily walks if you need the motivation to get outside more. Take a look at a small mammal, fish, bird, or reptile. Even if they aren't quite as friendly or cuddly, they can still make excellent pets. Before making a choice, just educate yourself on their care; some require specialized diets, while others may live for years longer than you're willing to commit to.
