When you are starting a company, you don't need to decide what you are going to be you should actually focus on what is really going to sell and, can you really add value? In the process, can you learn? It's obvious that you have dreams and aspirations. If they are very big, such as wanting to create a very large company, then focus on finding something very unique that you are going to do. If you don't find it and you still have that ambition stop. It's ok to close down the business if your ambitions. But if it is not, then know in your heart that you still have a better company and have gone through the same pain that other companies have gone through.
