I would have spent every single day with my sister before she left to live in New Zealand. At my wedding, it was the first time I had seen her in two and a half years.

I wouldn’t change anything. Life is what it is, you just have to get on with it.

But the market was changing. The industry was changing. The scale was changing. And in the end we knew we would be either the last company to make it or the first to not make it. We were right on the edge. We thought we would be the last one that made it, but we were wrong. We were the first one that didn't. We put an end to the companies that tried to do that. We certainly made our fair share of mistakes, but in the end I think we should have taken a bit longer to realize the world was changing and just gone on to be a software company right off the bat.

Resourceful, resilient and compassionate.

Becoming more physically active.
