Lessons are great! but you can also teach your self. Chances are though that you will become frustrated and discouraged at times.
If you wanna try to teach yourself here is an ok site: http://www.personal.psu.edu/users/f/p/fpm108/glw/lessons/index.htm
there are better, but i lost them on my HD.
But above all practice and when you have a question, remember that the answer is practice!
or you can go to lessions and suppliment with teaching your self, if your teacher doesnt care, and wants to reteach you it all because he wants more money for longer lessions :)
