The ability to look forward

Vision. Imagine walking everywhere with a cap brim so low over your eyes, that you can only see your feet when you walk. You can't see anything beyond that. You cannot see the cars, mailboxes, pedestrians, trees, or anything that might come your way. That's what it's like if you don't have vision.

Without a vision for the future, for what lies beyond, you will not be prepared for the inevitable obstacles. You won't know when to change direction. When brace yourself for a coming problem and prepare for it. You need to look beyond the present and envision what your company will look like in 10 years. And then persuade others to see that same vision and invest in it.

Communication

Communication. There's a video on YouTube of a dog running down a sidewalk in a small town barking at two police officers. The cops could tell by the dog's movements and tone that he was barking not out of aggression, but because he needed something. The policemen followed the dog and discovered a burning house with children inside. Thankfully, they managed to save the kids as the house burned to cinders.

Despite the obvious interspecies communication barrier, the dog was able to communicate that something was wrong so that this problem could be solved. Far too often, a young startup founder will identify a big problem or a big need and spark a great idea for how to solve it, only to discover they aren't very good at communicating the problem and solution to investors. If you cannot communicate the problem, solution, and why you're the right man or woman for carrying out the solution, you'll have a hard time convincing investors to part with their money.

The best way to improve your communication skills is baptism by fire. Go out and, well, communicate! Do it often and soon you'll learn the nuances and intricacies of effective communication. Hand gestures, head movement, tone and timber, reading the other person, etc.

Persistence 

Persistence. You're going to encounter obstacles. I know, breaking news, right? You'll hit a snag here or there. Someone won't like your idea. An investor will pull out. Something. But because you're serious about making it, you have to just pull your collar up and face the cold winter wind. Keep marching forward. However, there's something I like to call "intelligent persistence."

Let's say someone doesn't like an idea you have. Maybe they don't think it's wise to add a flap to your what-cha-ma-whos-it contraption. Persistence doesn't mean don't listen to them and persist anyway. No. Intelligent persistence is listening to them, making a decision based on the feedback, and persisting with a more intelligent direction in mind. You have to listen to feedback, both the good and the bad. Persistence doesn't mean to ignore the bad. It means listen, get enlightened, and make a more educated decision in moving forward. Don't let the bad stuff drag you down. But don't go forward without learning from your negative feedback either.
