28. Become a pet parent
If you mostly stay home or working from home, this is one of a few hobbies that will benefit you and some animals in need. Feeding animals is an amazing hobby, and it will make such a difference to living life.
If you're an animal lover but can't fully commit to having your baby, this might be ideal. Providing an animal space in your home will help it get accustomed to humans and are more likely to be adopted.
