Starts from looking after my Social media, updating those, answering back to the messages, prioritising, booking appointments, maintaining my calaners, writing the business plan/proposals, showing me analysis, scopes, everyday reports, scrap the competitors latest prices and let me know, checking my emails, answering those which are urgent and need to address, remind me my meeting & what to discuss and prepare a note for me, I mean a true personal assistant and to brainstorm with it about any problem……. Etc etc etc lots of things an assistant does
