Experience
This is my first attempt to publish a photo from my LG mobile phone. It's a bit of a hassle, and the quality sucks, but there's nothing like being there.
It was an intense day spent weaving potholders. I don't remember the last time I enjoyed concentrating so much on anything for so long. You can learn a lot from a course like this, and then there is stuff you can only learn from experience. There's no shortcut to experience.
