I haven't modelled since I was 12 - that was a one-time thing, and I did it as a kid to make a little money to save up for university. Acting is my first love as well as writing and eventually producing and directing.

As I have discovered by examining my past, I started out as a child. Coincidentally, so did my brother. My mother did not put all her eggs in one basket, so to speak: she gave me a younger brother named Russell, who taught me what was meant by 'survival of the fittest.'

Startups need to focus on building a foundation for their company culture early, and then they need to revisit it often. Every time a hire is made, a feature is launched, a Facebook status is updated, a press interview is given, a round of financing is raised, or a meeting is held, culture should be part of the decision-making process.
