Has anyone done this?

I need a hobby. The last of my hobbies I gave away just before I got pregnant with DS, (I was ready to give them away and not ready to go back right now) and I'm now finding that I've lost myself. All I am is Mum at home and then employee at work and I have nothing that is just mine, just for me without interruptions.

I do like crafty things, but with limited space and two small children around I just can't give it the attention I want to. And it also means constant interruptions because I'm there.

So I would like to find something that a) gets me out of the house and b) is appointment based so that I have to go and not procrastinate or get distracted.

So, two ideas - one is horseriding and the other is dancing (probably tap). I have tried picking up dancing before but found that even though I was in a beginners class, the rest of the class were people that learnt as a child and are now basically just refreshing. I'm an absolute beginner and so found i got left behind right from the start which disappointed and frustrated me. The only way around this is private lessons.

And horseriding, well, everything I find is based around the idea that I am researching somewhere for my child to go. There doesn't seem to be much for total beginner adults. I don't just want to go on trail rides, I want to learn. Again I think private lessons will be an option, but it gets kind of exxy if kept up long-term.

Has anyone else done this sort of thing? Can you tell me your experiences?

Has anyone got any other ideas? Please don't suggest local short courses, I've looked in to them and there isn't anything that particularly interests me around my area. But I am open to other suggestions!
