Plastering

Today is Saturday, which means that my husband and I work on our house with his parents all day. I got a lot of plastering (some people call it mudding and taping) done. I have the hang of the screw holes and I can even do them without sanding in between the layers first but the seams and corners are hard. I've been shown how to do them but so far, it hasn't made them any easier. Anyone have any technique suggestions? (Let me know in the comments!) It just seems like this should be easier than it is. It looks really easy to do in the videos but that can be true of anything when the person knows what they're doing. So, just let me know!
