"I'm not talking ideas, or even presentation. It's like in politics: You have to sell something to become an electric player - like your skin or your heart"

This quote by Keith Jarrett is referring to the concept that in order to achieve success in any field, you have to want to put yourself out there and make yourself vulnerable. It's insufficient to just have great concepts or a good discussion; you have to want to put yourself on the line and make yourself an appealing alternative to others. This resembles politics, where you have to be willing to put yourself out there and make yourself an attractive alternative to voters. You need to be willing to put yourself out there and make yourself an appealing choice to others, whether it's through your skin (your physical appearance) or your heart (your emotional and mindset). In order to be an electrical gamer, you need to want to put yourself out there and make yourself an attractive choice to others.
