Later, William went to another blood testing laboratory. But this one was a public health laboratory. And the system worked very differently. There was no need for as many workers. Instead, there were machines!

This was a better method. It saved time and human effort.

People will always produce results that are a little different. They are not machines! But a machine does not make human mistakes! It produces exactly the same results each time. William thought this method was excellent!

And then, he had an idea! The chemistry laboratory had made him think of a kitchen.

He also thought of the struggles people had in making sadza. Machines could make sadza! They would save time and effort. And machines would prevent human mistakes.

William knew that he had a good idea. But he also knew that he was not yet ready to create the machine.

He needed to study more before he could make his idea work.

He said, 'I needed to do a lot of work to make this idea into a business. I needed financial management. Most new business people fail in this area. So I went and joined a firm.'

At the firm, William worked hard to gain the business skills he needed. He was patient.

He knew the time would come to make his Gwatamatic Machine. William knew it was not going to be easy. No one had ever built such a machine before.
