Listen, there's no other solution to your issue other than trial and error. There is no tutorial that's going to teach you exactly how to do it, you have to learn. Gradually. With experience. So go and try your best, and if you have any questions, ask. And what I mean by that is be specific, down to the detail. What do you want to know?
Please also keep in mind that animation is subjective. Everyone does things just a little bit differently and that's what works for them. Everyone has their own style. You need to build your own set of habits and your own style, on your own.
