Any business today that embraces the status quo as an operating principle is going to be on a death march.

It's not the things you don't know that trip you up. It's the things you think you know, but you don't. You fail to ask a certain question because you believe you know the answer. Separating your information from your assumptions can be very tricky business.

Just like the Internet disrupted the publishing industry, we're going to see Bitcoin micropayments creating some very interesting opportunities for pay-as-you-go, pay-based-on-time online businesses and, frankly, some risks as well to the traditional business model as to how things get sold online.

There was a point in the late '90s where all the graduating M.B.A.'s wanted to start companies in Silicon Valley, and for the most part they were not actually qualified to do it.

The majority of men meet with failure because of their lack of persistence in creating new plans to take the place of those which fail.

I don't create companies for the sake of creating companies, but to get things done.

The opportunity is often lost by deliberating.

What makes 'Maybach Music V' so special was, of course, I put the album out celebrating my daughter's birthday as well, and DeJ Loaf is her favorite artist. So 'Maybach Music V,' I wanted a real airy type of feel. Just a real slow vibe to it that's also going to surprise my daughter. So that's real special.

I spent my 21st birthday chatting with my online friends because my husband had little interest in celebrating with me, and there was no other group of people I'd rather spend time with, even if they weren't there with me in person.

I have heard of 'Green Street'-dedicated birthday parties, a website dedicated only to the clothing. It has no end. If you hashtag #greenstreet or #greenstreethooligans, you cannot go a day without people saying it's their favourite movie. It's frustrating because it's a massive hit, but nobody gives it credit.

Having a birthday around the holidays was never easy and, with every successive year, it felt more and more as if celebrating my birthday got thrown into the December holiday mix as an afterthought.

I remember debating the finer points of flaky pastry with my chicken-pot-pie-obsessed American dad. I remember the divine mix of Thai food, TV dinners, and hearty, homemade goodness that have shaped this palate of mine to this day. I remember all this, but I still Google my husband's birthday. Thank God he's famous.

I must have been yearning for some Jewish content beyond my genetic makeup because soon after my 21st birthday, I noticed I was no longer dating WASPs.

I turned 40 on the set of the reunion show for 'Sheer Genius,' so it wasn't a hideous birthday because I had everyone on the cast and crew sing 'Happy Birthday' to me, and I won $10,000 for being the fan favorite. It was really liberating to turn 40 and realize that I felt very comfortable with myself and knew who I was.

The thrill of performing - that's something that hasn't changed for me. That simultaneous joy of creating something and sharing it with an audience - it's the same now as it was then, when it was just my cousins' birthday party.

As far as those kinds of things, I also played at the concert to call for the release of Nelson Mandela when he was a political prisoner in South Africa. We were celebrating his 70th birthday and calling for his release.

Early on, when my wife and I were dating, we went to the grocery store, and I told her that sometimes I just buy birthday cakes, and I eat them. And she said: 'Really? I do, too.'

I just remember celebrating my 18th birthday at home, so that was a big party.

That's the great thing about New Year's, you get to be a year older. For me, that wasn't such a joke, because my birthday was always around this time. When I was a kid, my father used to tell me that everybody was celebrating my birthday. That's what the trees are all about.

You should feel good about making your home nicer for your family and your friends. You should feel great about cooking a good dinner and making a dress for a granddaughter, creating a beautiful birthday party. It's all part of life.

It is ironic that the one thing that all religions recognize as separating us from our creator, our very self-consciousness, is also the one thing that divides us from our fellow creatures. It was a bitter birthday present from evolution.

If I could be doing anything, I'd be laying on the floor in my birthday suit eating junk food and watching something dumb on TV.

My policy on cake is pro having it and pro eating it.

Skydiving is fascinating, the best part is cruising in the air and realizing that the dice has been thrown and you're either going to die or not. It's a very helpless feeling but it's so freeing.
