I read Frankyl's book a few years ago. But I still struggle with what my life's purpose is. What I have done is volunteer at an animal rescue. They are a no kill organization and get most of the animals from kill shelters, provide them with whatever medical attention they need, start them on their vaccinations and spay/neuter them. They are then sent to the no cage adoption center. This organization is becoming the national model for animal rescue.
I am shy too, but there I have something in common with other volunteers and the staff. From there our friendships grew and now I am comfortable.
I chose animal rescue because that is something I am passionate about. Also, they don't have a requirement for when or how many hours/days I have to be there. Is there someplace you can volunteer?
