I would recommended doing this kind of work in your spare time - perhaps on the weekend to ensure your passion for caring is a lasting one. Many of us have hobbies and things we do or take part in that we love and are passionate about; but doing it everyday may take that passion out of it completely. If you are sure that caring is something you want to do, then I say if you are happy to take the drop in salary to fulfill your life purpose then go for it! Life is so much more fulfilling when you are doing what you have been designed to do!
