Of course, you need to use your camera carefully. One obvious example is that you should avoid falling it on the ground or from scratching.
You must understand by now that a camera can be very expensive, and it will be very painful if you break it and then you need to buy a new one—just after you bought the original one.
Also, as a professional photographer, the camera is just the tool that you use to make a living. Therefore, show respect to it. Do not throw it on the sofa when you get home, and put it nicely into the box or on the table.
