Doing technically brilliant work may be enough for your personal gratification, but you should never think it's enough. If you lock yourself in a room and do the most marvellous work but don't tell anyone, then no one will know, no one will benefit, and the work will be lost. You may have derived personal satisfaction from it, but as far as the wider world is concerned, you may as well not have bothered.
