I think if you want to have more fun coding then ignore standards, documentation and whatever else you do to be a responsible programmer which also slows you down. If you're coding for yourself, you can code as 'badly' as you want, ignore standards and use your own conventions, come up with your own systems, and make things useful for other parts of your life. You can add bits and pieces as you go, and there's no need to be burdened by what other people think.
