For the next 2 ½ years you'll find yourself at the beck and call of a demanding employer. Unfortunately, it won't be easy to tell if this person's demands are reasonable or not. If the demands are meaningful, then this will be a truly educational experience where you learn more than you ever could have before. If arbitrary then this could devolve into a tedious indentured servitude. Whether you're learning about what to do – or what NOT to do – this period will still be worth the travails. It's all meant to set you up for the day when you take on the mantle of authority.
