Whether you are into Classic Video Games or not, I hope you got the message - Practice is the determining factor when you are progressing toward your creative potential!
Keep on practicing - and try and remember that practicing allows you to make mistakes without consequence, try new things, and makes you omniscient of the things you practice.
