practice = shoot anything you like
Try challenging situations, like low light, against a bright light, low speed, high speed, shallow or large depth of field, handheld, or in a tripod, ambient light, flash, closeups , night images, the idea is to understand how the camera works in the different situations, and what parameters are needed to obtain the image that you are looking for.
I have no need to print unless I really like a picture , I review my images on the computer
Everyone will have their own method to save pictures, my method is as follows:
- I save the raw images (I rarely shoot jpg)
- Also save the processed version if I really like the image
- Keep 3 sets of copies of my images in separate hard disks, which I sync monthly or more frequently if I went to an important photographic event
one more comment.... it does take a while to learn, so be curious about new things but also be patient
