I think some are helpful - but yes, it is important to use your camera. Whenever I get a new lens - for example - I take pics around the house and wherever I go. In turn, I learn the nuances of the lens and how it renders. If it’s a new camera then I learn the menu system, adjust to the shutter lag, etc.

Collectively I may even establish a fondness for a new genre if it’s a result of shooting something available to me.
