Organic clutches are really intolerant of slipping while they are breaking in, and tend to stink really easy if heated before they are fully broken in. While the car is new and breaking in, you need to be really careful, as you can hot spot the flywheel and then the clutch will feel like garbage until it's replaced.
A few times aren't going to kill it though, so if you are a bit more careful through the rest of the break in process you should be fine.
