Does the extreme weather of European countries help them for growth or destruction?

My presumption:

The extreme cold weather enables the person to have DEEP THINKING and DETAIL Planning? Thus 3 to 4 months of extreme cold period when a person almost hibernates, he can utilise the time to  concentrate on all his thoughts and mould them into some creative PLAN.

This PLAN can result in

• Research
• Discovery
• Great Literary books
• Great piece of Arts and sculpture
• great inventions which helped industrialization

and same element is used for

Plan for wars and destruction!

TWO sides of the same coin.
