Hey RaspberryAlice!
There are a lot of people on here that have started over after a long hiatus, myself included! It can be really frustrating. And, going from the structure of a studio to the wishy-washy time on your own at home can be really difficult, too, because it's hard to create that kind of mental and physical space for dancing, for learning, and for focus... especially when you don't have a specific room for your pole, and it's just hangin' out in your living room ;)
Also I don't think I've ever seen anyone ask "Why should you care?" On this forum. Rest assured, if you need help, we care! This community has been wonderful. I've been here about 5 years, and I just keep coming back for more!
So, my first suggestion would be to slow down! I'm sure you feel that this is obvious, but reminding yourself to slow down and enjoy your rediscovery, and get back in touch with your body, can really do wonders. Avoiding an overtraining injury is pretty key with pole dancing, so see if you can find the great things about going slow and really getting into your beginner moves, and your flow!
Next, for aid with grip, since you mentioned you don't have any "tacky stuff"... as a beginner, I've never found I needed it! So, key points there would be to make sure your pole is warm, and that you are warm, before starting work on your new moves in which you need to stick to the pole. Something like a pole sit can be super difficult when you, your pole, or both of you are still cold!
In order to create the space you want and need to get pole dancing and really enjoy it, you can build your own "class structure," if you like. I've found it useful! I start off with a warm up, get into some freestyle, and then work on the more difficult moves I've been trying to get. Afterward, I move on to strength work, and then finish off and cool down with stretching and flexibility training. You can keep it super simple!
I often find that working on two or three moves at a time gives me enough variety, especially if I'm really struggling with one of them. One move is just a bit too little, and I get bored. Too many, like four or more, and I get confused and out of focus!
I would highly suggest Veena's 30 day Takeoff, as it can introduce some great structure into your pole life. And, Veena's library of moves is actually all in order of difficulty, so if you find yourself feeling like you're pushing too hard, you may want to backtrack and see what else you might learn!
