Most of the top companies today started in an ignoble way. Started so small and weak that no one felt threatened by their existence. A lot started as an extension of some youth's project or hobby. Microsoft, Apple, Yahoo, Google and Facebook. And the one thing they all have in common is that they grew fast and for a long period. They were all ignored by the competition, even experienced being turned down by the competition, only to end up ruining the competition. Yahoo is being rendered obsolete by the very Google it refused to buy at a giveaway price. Amazon is wiping out an entire industry. Netflix killed the very company it begged for a business partnership at the start.
To seek growth is to keep pushing the limits, to keep attempting what no one is thinking of in the industry and to spend all you have on innovation. It's the only way companies grow and keep growing. The companies that stop innovating must spend all they have on acquiring the ones that are innovating or risk dying.
So if the companies you invest in are growing by spending their money on innovation why should you not be innovative? Why should you not seek your own growth by being at the innovative edge of your expertise?
Why aren't you seeking growth?
