Maybe because it's entirely an artist's eye, patience and skill that makes an image and not his tools.
The camera's only job is to get out of the way of making photographs.
You need to learn to see and compose. The more time you waste worrying about your equipment the less time you'll have to put into creating great images. Worry about your images, not your equipment.
No matter how advanced your camera you still need to be responsible for getting it to the right place at the right time and pointing it in the right direction to get the photo you want.
Your equipment DOES NOT affect the quality of your image. The less time and effort you spend worrying about your equipment the more time and effort you can spend creating great images. The right equipment just makes it easier, faster or more convenient for you to get the results you need.
