I've had a Rubix Cube forever. Like many other people, I never did know how to solve it. I could do a single side just fine. Then one day I did two sides. And by a sheer stoke of luck I solved three sides and left it at that. Of course I knew there was no way you could solve each side on its own to solve the whole cube.
Today I decided that I was going to learn how it's done. And I did. It took a while and I still need practice, but I can now say that I have solved a Rubix Cube.
