Hey there!
I've noticed that a lot of people find a lot of benefit from going to classes in person, as they are a way of being held accountable- you go, even though you don't really want to, and often end up having a really good time anyways.
And, this is the plight of "motivation." Motivation, as a thing that applies to any hobby or activity, is an emotion. It's not going to obey you, and it's not something you can have every single time you look to do that activity. It's something that is a bonus, the icing on the cake, that gives you a little extra energy, and helps you come to the activity with excitement, even if you aren't doing anything exciting.
However, it's not something to rely on when you want to pick up something as a hobby, especially exercise. Exercise is served best consistently, it's something that we benefit from when done often. You need to put in the hours. This is also true of most creative hobbies, but most people aren't looking to get strong or "lose weight" with a guitar. These results you will see from putting in the hours, and making sure you put them in.
So, even when you don't want to get on the pole, if it's time to get on it, just get ON it. Put your pole clothes on and do some things you like. Put on a song you've been jamming to lately and just move your body, however awkwardly, to it. Get sexy, or sporty, or rough- whatever you are looking for that day. Do it, because the hours you put in when you don't want to are the ones that will pay off the most.
And, chances are, you'll come away from it happy, or at the very least, proud that you fought your way through and finished it when you said you would. You're making a promise to yourself, and then you're keeping it.
No more racing driver's excuses, no more listening to the emotional self (which, more often than not, just wants to rest or cry or watch cat videos, or whatever else), and get on that pole. Work it. Say good things to yourself about your working it. Tell yourself that sometimes it's okay to be gentle if you're getting tired early, or that you don't ALWAYS have to work on the toughest moves. Work it because you know you want to, because your long-term goals are greater than short-term gratification. Work it because you said you would.
And yes, I've found the lessons on here to be more than sufficient for learning pole dancing ;)
