Words of wisdom from uber-tech blogger John Gruber on his blog Daring Fireball:
Market share as a first priority generally doesn't end well. When you compete on quality, “almost the best” will often still do pretty well. When you compete on price, “almost the cheapest” always loses.
His words may have been addressed to the tech industry, but they could easily be applied to most of our life endeavors.
When you look at all the successful ventures around you, you are not necessarily looking at THE best, the MOST well known or even the most popular. Success does not demand such stringent and narrow standards from you. It just asks that you do YOUR best.
