Starting a business is not about the big idea you have. Very seldom does someone come up with an earth shattering, ground-breaking business idea one day, and change the world a few years later. In fact, from my experience, the companies that do change the world tend to come about quite randomly, and the ones that started with an earth shattering idea tend to go bust.

Take Facebook for example. Mark Zuckerberg didn't invent social networking. He stole the idea from a couple of twins from Harvard who hired him to help build a website based on an idea that they stole from a company called Friendster. Six years later, Zuckerberg is a billionaire, the twins made cash by suing Zuckerberg, and Friendster is looking to sell for far less than their investors would hope for.

Twitter started as a side project. The original idea was completely based around sending status updates from your mobile phone. A few years later, that basic idea is still very much a part of Twitter, but it's turned into so much more. It's a new form of communication and it's changing the world as we know it.

The funny thing is, it took Twitter years to even understand what their idea REALLY was. Go look at the new homepage. It's all about real time search. What's happening right now? That's what Twitter is. Well, until three weeks ago, you could go to the homepage and the about page and any other page on the site and have no idea why Twitter was actually useful. The founders didn't even know. It took a lot of money, a ton of hard work and a lot of smart minds to wrap their heads around what the idea actually was and then figure out how they could present it to the world.

The point is, entrepreneurship is not about a big idea. It's about execution and it's about a whole boat load of little ideas that come from assembling a smart team of people and giving them the freedom to innovate.

That's why I loved reading about the new initiative by YCombinator. They will be issuing RFS's or Requests for Startups. Basically they give some ideas of what kind of company they are looking for and they will accept the entrepreneurs that pitch the best way to get the idea done. Obviously the people at YCombinator understand that startups need an idea, but the successful ones are the startups that make ideas come to life.

Over the past two years since starting Brazen Careerist I've realized this first hand. When Penelope and I first discussed starting a company, we had no idea what we were going to do. We knew the market we wanted go into, and we knew that we wanted to help people with their careers, but that's about it. No crazy ideas to change the world. Just a desire to do something great.

Since then, we've all had a lot of good ideas and a lot of bad ideas, and the whole team has worked their tails off to make this whole thing come to life. And finally after a couple of years, we have a pretty good idea of what our business is. All it took was not being able to pay rent occasionally, showering and living at the office some days, working when we were supposed to be sleeping, and cheering our one-man development team as he coded until 6 am.

All that stuff is called execution. And that's what running a business is all about. Every startup that's lived on for more than a couple months has done the same thing, and every successful start-up will continue to do the same thing.

My point is this. If you're dying to be an entrepreneur because you're full of ideas, just pick one. Put a plan together, create some milestones, pitch in some capital, recruit a partner or two, hit your milestones and execute on the plan that you created. Be prepared for sacrifice, instability, arguments, being terrified, and a serious lack of sleep. Because that's what the game is really all about. Your idea is just the beginning.
