December used to be very difficult for me. For many years, I fought the transition to the new year, was generally exhausted at the end of the year, and just wanted to hide. I described myself as a 'cranky Jewish kid who felt left out by Christmas.'

If you don't have a VP Finance on your team reporting to you, do yourself, your team, and your investors a favor and go hire one right now.

I'm a strong believer that you can build great companies in time of both greed and fear. But you have to be paying attention and operating under the right assumptions. You don't have to believe history repeats itself, but you should accept that history rhymes.

Having read my share of tell-alls over the year, including some that were passed off as autobiographies, I mostly feel sad - sometimes for the writer and sometimes for all the people in his way. I hope that the process of writing the tell-all gives some release and closure on what clearly was an unpleasant and unfulfilling life experience.

Technology doesn't address everything - for example, air travel still sucks.

I'm a venture capitalist. I like to say my job is to help and support entrepreneurs. I can play a leadership role, but my organization can't be the leader.

I believe that all men and women are created equal, but it took our country until 1920 to acknowledge this for women. And then it took until 1964, the year before I was born, to outlaw discrimination based on race, color, religion, sex, or national origin. And same-sex marriage became the law of the land in 2015.

While we should certainly be investing in our own STEM education, we should take advantage of the thousands of international students who come here to study and are ready to fill these gaps immediately upon graduation.

I have several close friends who are insomniacs. Over the years, I've heard their stories about being up in the middle of the night, completely awake. I see them yawn at 11 A.M. and know that, regardless of what they are doing, they'd probably rather be in bed sleeping. I've always had sympathy for them, but I've never really understood it.

As a teenager, my dad taught me about the idea of unintended consequences, and I've had the experience, and how to deal with it, pounded into my soul over the years.
