Entrepreneurship is what legos were to you as a kid. You see some pieces and you see the potential to make something unique out of them. And then there is innovation - that's where you see those pieces and you wish you could make some of custom sizes and shapes to make a creation that is truly original and unique and perhaps even functional.
I think this is largely opinion based - however I would say developing a platform with high expense and no functionality for monetization.
Take what you think will be invested into your project - multiply by .25 and that will be double what you actually get.
Heavy investments will come - at precisely the point you probably don't need them anymore.
You only get ONE chance at a first impression.
Diversify! Then support the diversity or be crushed beneath it.
Starting my career in an advanced Technical Rating in the US Navy I moved to the civilian sector to do Tech support moving on to Server and Network Administration and finally to Programming. Continuing to learn and grow and expand my skill base I moved from scripting and basic programming in Visual Basic and Flash Action Script to more powerful languages like C# and Java. Following several years in high paced and intense programming environments I am now working heavily with Microsoft MVC and mobile applications.
