This is actually one of the great entrepreneurship lessons of my career, which I think about a lot.
Around 2009, as smart phones were on their exponential leg up, and when I was still pretty new in the workplace, I remember thinking (and talking with my coworkers) about how messaging and chat rooms were really well suited to the technology landscape. But I lamented "too bad the space is already too crowded with options for anyone to use anything new.
But all of today's major messaging successes became household names after that! What I learned from this is that I have a tendency to think that trends are played out already, when actually I'm early in the adoption curve.
And markets are growing.
