I don't know what kind of job you have, but that won't fly in an actual career. You have to do things you don't want to do; that's just part of life.

It's simply impossible not to be motivated. Your body will force you to breathe, drink, eat, and sleep. If you're doing other tasks, you're motivated to do them by some force. That doesn't mean that you're out there writing inspirational thoughts about doing them, but something is causing you to desire to complete that action.

Let's say you want something to eat. You need food. For food, you need either money or a farm. You choose money, so you need a job. You're motivated to have a job, because you want money to pay for food.

Let's say you collect stamps. You can't point out the exact reason you like collecting stamps. Maybe you inherited the collection and felt the need to continue it. Maybe you want to have the biggest stamp collection in the world. Maybe you want to preserve little pieces of history. Maybe you just like stamps, which ties in with what you said. You just enjoy doing whatever activity it is. That's motivation. You want to feel a sense of enjoyment, so you do said activity.
