You have to use it

Love this quote from The Wizard's Butler by Nathan Loewel

“You might look around for something you always wanted to know, but without a use for that knowledge, without engaging your mind in it, it’s useless. It’s not exercising the parts of the brain that it needs to, to get the benefit. People just give up when it doesn’t keep their attention, or doesn’t seem as interesting as it might have been.”

Photography is very much a use it or loose it skill. Shure you can point a camera at something and press the button but that's just a snapshot, it’s not taking a photograph.
