See yourself as a skill set and not as a job title and you will develop a fluidity that will keep you employed for a lifetime. We get stuck on preconceived notions of what we should call ourselves creating a box that traps our creativity and limits our opportunities. Skills are the knowledge and expertise you acquire through education, training and life experience. They do not require money or payment in order to be valid therefore it does not matter if your skills were developed through seva (selfless service), or employment. And do not let your ego inhibit your ability to tell others what you are good at. This keeps you small and unable to serve at your highest ability.
Own what you bring to this world so that you can get to work helping to change it.
