All the above, and gradually learn to look at light and the way it falls on & reflects from the world, and how it records in photographs ( two complementary things).
Look at published photos, examine your feelings about them, be yourself but remain open to possibilty, and ask why you like them or don't.
There are a thousand ways to see, photographically. Look at black and white for a graphical distillation. Colour's more subtle in a way (and more limited in another way, being more literal).
There's light and life, and the rectangle (mostly) of a photograph is a creative confine.
To engage with the medium, forget about what you're thinking of photographing - just assess the light.
The journey is huge and endless, but it's ok to wander gently, sometimes bumping into things. Life, not photography, is the centre of life, after all.
