Why Peruvians Put Things Off Until Tomorrow

Growing up I hear the story of the grasshopper and the ants. During the summer the ants worked hard and stored food for the upcoming winter. The grasshopper, on the other hand, played all summer. When winter came he had nothing. Luckily, the ants took pity on him and gave him food. It reminds me a lot of the Peruvian mentality.
Because Peru is generally a warm country, planning really isn't needed and the country can't move forward. There are a lot of theories (source) about why this may be true. If you're really interested in this topic, I recommend reading Why Nations Fail: The Origins of Power, Prosperity, and Poverty and How Rich Countries Got Rich and Why Poor Countries Stay Poor.

1. Cold air makes people more vigorous and increases the size of their brain. (Source)
2. Frost makes the soil fertile and crops grow better in places further from the equator.
3. Due to the fact that there are a lot of diseases around the equator people have to spend more time and effort trying to prevent the diseases and can't use their time to do other things.
4. Animals were domesticated away from the equator so those countries have had a head start.
5. People in warmer climates have year-long access to food and can live day by day.
6. Heat makes people lazy. No one wants to work when it's really hot.
7. In cold climates you can't do much during the winter except think.
