In the beginning, God created the heavens and the earth. There is a big debate over how long it took in terms of human-scale time measurements. However, there are two things we can all agree upon. First, God did not create the heavens and the earth in an instant. Second, God did not create it at a go. He created it step-by-step over 7 time periods (each time period referred to, as a day in the Bible). Stories and movies have painted a picture of a genius that can create anything in an instant or a few hours. This is not consistent with reality.
The goal of any creative venture is to come up with something new and useful. You should never underestimate the amount of raw effort that is required to produce something that is original and useful. You should close your eyes for a minute and think about your favourite product or company or preacher. Think about how they have improved over the years. Investigate their origins, the original ideas that drove the first step. The amount of time it took to produce the first version of the product. Find out all you can about the Apple II computer, and compare with the latest version of the iPhone. You will understand how creations evolve over time.
A new invention begins with an idea. The initial idea is more likely an idea about an idea. Ideas do not come to you fully formed. It is as you set out to work on the initial idea that you gain better perspective and feedback to make something good out of it. That is why you will need a lot of time and quality feedback to evolve an idea into something useful and perhaps, indispensable. You will not create it over the course of a single day. These things take time and energy. Go to work on your ideas, get feedback early in the creative process. Your initial idea might not be so impressive, but as you improve it, there is no limit to how far you can go.
