Crocheting is easy once you understand the basic concept, which is starting with a slipknot, you use the hook to pull the yarn through to make a loop. And just keep pulling one loop through after another to make a chain which is basically a series of slipknots.
To go back for the next row, a single-crochet stitch just means putting the hook through the loop of the previous chain-stitch, and pulling the yarn both through that AND the current loop that's already on the hook, to make your new loop. once you can do those two things, the rest is just variations.
You don't even need a hook to practice, if you have some yarn and tie a slipknot, reach thru the loop with your fingers and pull a loop of yarn thru, and again, and again, to make a finger-crochet chain.
The hook takes more practice, there's a rhythm to it, grab the yarn, twist the hook a bit so the yarn is hooked good while you pull it thru, untwist, grab the yarn, twist, pull it thru. With your other hand in sort of a Y shape, or like you're making shadow-puppets or something, thread the yarn over your pinky, under your ring and middle fingers, and over your index finger, then grasp the work with your thumb and middle and ring fingers. Threading it this way, you keep tension on the yarn and keep the section you're working on straight. The tension takes practice as well, to keep uniform stitches.
Don't try tightly spaced items for beginner projects. You will get frustrated with keeping the right tension without getting the hook stuck in the loops. Start with fat yarn and a fat hook, and a nice simple loose stitch. And remember, some variation will even itself out with washing and use.
