I used to play violin when I was younger. Started in elementary school, played during some thing that met once every so often at school. After some time, I don't remember how long, I got some private lessons for a while. Two or three years at least. In any case, I didn't try very hard, I didn't practice enough, mostly. I eventually stopped. I feel kinda bad about not trying harder, because it was somewhat of a waste of my parents money.
However, I recently got the urge to play again, and I've actually started practicing. I've gotten a good few hours a day for the last few days, and I'm having a lot of fun. I'm not very good, but the foundation I got from some lessons was enough that I should be able to get somewhat better without any lessons, at least for a while. I may take more in the future, however.
