Come on guys. Is the goal in trying to get it right about pleasing the audience or not looking stupid? A bit of both I suspect for me and many others. Beginners start out thinking too much about themselves rather than the audience. As you become more confident you swing towards pleasing the audience. Interestingly, you can swing back the other way without realising it (eg. by not doing new material)in an effort to keep pleasing the audience. I guess it's easy to forget about what the audience is looking for so I prefer 'unaware'. Selfish (or arrogant) is the person who says 'I play what I want and if they don't like it, tough'.
