I have many qualities that would qualify as an assistant.
I was an office assistant for the State of California for many years. This position brought me experience in data entry, administrative assisting, human resources, appointment setting, managing calenders and appointments, managing state agency files, etc.
I currently run my own small business which requires many skills that would useful as a personal assistant. Such as, balancing my books, data entry, website management, product/stock management, invoicing, etc.
