I am always impressed by how successful entrepreneurs share the ability to calmly solve big problems. They understand that you don't have to have it all figured out ahead of time but you do have to have confidence in your ability to come up with solutions.
That is something our educational system needs to do a better job of developing. We learn at a very young age that mastery of information and detailed preparation is the best route to career success. But this creates a culture that is afraid to take risks unless one has it all figured out in advance.
Our society would create a lot more quality jobs if we trained individuals better to use information to confidently solve problems…not to hide from them.
If you want to start a new venture, develop your confidence muscles. Learn to trust that every problem creates new opportunities and that you have what it takes to find a solution.
