I love being rich! But I wasn't always rich. I was a poor landless peasant before.... it took me some luck, energy and guts to become a successful, adventuresome merchant.
I had to walk great distances to become successful. I walked all around Europe trying to find goods that I can bring back home to sell for a lot more. My tactic is very simple buy the goods and sell for a lot more.
After some journeys I have so many goods that I need to hire workers to manufacture my goods. I also need to build warehouses to store my goods.
