Have you heard of Facebook?

It’s mid-2005. I’m sitting across from the CEO of a growing startup in what I hope – as a 23-year-old leaving the path of a journalism career to actually pay some bills – is the last interview for the job.

‘Guerrilla marketing’.

The CEO is kind, but my mind is racing as he now asks me to give some examples of the ways I’d engage in guerrilla marketing; ideas I could bring to the team. I’m racking my brain for a semi-intelligent answer – suddenly I realize how young I am – and the next thing I know I’m saying –

“Have you heard of Facebook?”

I still remember that day fairly vividly. It was the day I became conscious of something I think I’ve always done but never realized I was doing it: using personal experience to guide my actions, and the spirit of experimentation to create new opportunities for myself. For years, my CEO (and mentor) would remind me of how I blew his mind that day, as I logged in to my infant Facebook account right on his computer. There was a profile pic, the Wall, ‘too close for missiles, I’m switching to guns’. Facebook, just over a year from its own creation. Playing a random and active part in my career’s creation.

In a Jerusalem tech tower, there we were: 22-year-old me, a successful and recognized entrepreneur, and my contemporary, Mark Zuckerberg.

What I have pulled from that experience, which was the foundation of six years at Answers.com and the rest of my ongoing career, is that if you manage to become self aware enough, you can figure out how to use your own personal experience, worldliness, perspective, and spirit of experimentation as your guide. Shhh – do you hear that? It’s you, with the ability to feed your gut feelings. To build an idea into action. To learn a new trade. To become an influencer.

That day I opened a door for myself. And I got the job. And became a guerrilla marketer for as long as that was in style. Then a social media marketer, a content marketer, a marketing manager, a community manager, a brand builder.

Throughout my six years there, I learned so much about people. About high tech. About leadership. About startups. About Israel. About myself, as part of a pre-internet and post-internet generation. About early adapters. About humility and learning and biding my time.

My advice is, train in becoming self aware enough not to miss opportunities. But also self aware enough to know when it’s time to watch and learn and listen. That last part helps you know when the time is right to take opportunities, to take the leap of faith, to trust the brainstorm.

Maybe the best opportunities are born from the desperate need to justify your 22-year-old self. Or from knowing you have something to offer; you just need the guts to do it.
