Peter Ngugi is an architect of small money. He has spent most of his life understanding that a shilling is not really a shilling. It is a brick. Put enough of them together, and eventually you have a house. Even a mansion, depending on how bad your dreams scare you. 

He was seven when he started building. In rural Murang’a, he kept and sold rabbits. As a teenager, he grew sukumawiki. He was not thinking about wealth then. He was simply learning that small things, tended carefully, could become something. 

His plan was university. But that didn’t happen. Not yet, at least. His father told him there was no land or cow to sell for college fees. He had to fend for himself. He was hurt. “Mark this day,” he told his father. 

And maybe that’s when the Ngugi fire was lit. 

He became a turnboy and saved for university, leaving the money with his father. Six months and 27,000 shillings later, he went to collect it and found his father had spent it. There was a wound there, a slamming door, and off he went to Nairobi, where he did mjengo during the day and studied accounting at night. Then he got a job as a cleaner and messenger in a law firm. His salary was KSh3,500. He carried files, ran errands, climbed stairs in court buildings, waited outside offices. 

He also discovered another little piece of mathematics. A law firm always pushed paper, always photocopied paper. He found places to do that cheaper, saving 100 shillings daily, which he deposited at Post Bank. Small money one day grows up. 

Then, in 1998, terrorists blew up the building, killing the firm’s accountant. The messenger became the accountant. In 2009, he joined Securex as an assistant accountant, eventually completing the university degree that the C-plus had once kept from him. 

Today he sits at the top of the accounting office, overseeing the cash flow of a company with close to 6,000 employees and branches across the region. He has built a home, bought cars, made peace with his father, and raised a family. 

His children will not receive a fortune when they graduate, though. 

“They will receive a gas cooker. Two cups. Two plates. Two spoons. Six months of groceries,” he says. “That’s it.” 

Then they will build their own world. Because it is what he did. 

One rabbit at a time. 

The math doesn’t lie.
