Motivating an audience in any given direction is the ultimate musical challenge, and while I don't like every kind of music or musician I see, I always appreciate the testicular fortitude it takes to pull off a performance - and the results always speak for themselves. Now matter the instrument, if you are able to entertain and compete with other entertainers on an ongoing basis, you must be doing something right. If you aren't, you'll know it quickly enough. I've seen guys make their entire livings for decades off of arranger keyboards... obviously the ability to use an arranger keyboard to it's fullest potential is a profitable job skill.
