Characteristics of entrepreneurs

Here are the 10 characteristics of most entrepreneurs:

• You are driven by motivation and ambition
• Highly disciplined
• Leadership, planning, and management skills
• You are proactive and take initiative
• Learn from your mistakes and the mistakes of others
• Realize that success is the only option
• Willing to exploit new opportunities
• Knowledgeable of the subject matter and willing to learn more
• You prefer the excitement of risk
• You are committed no matter the obstacles

Attributes of Successful Entrepreneurs

To the right you will find a list of attributes that many entrepreneurs share. I believe though that although all of those can be found in many entrepreneurs, successful entrepreneurs usually have the following five attributes.

• Ambition - The desire to succeed is a key attribute determining the success of an entrepreneur. An entrepreneur must be passionate about what he/she is doing and truly believe in the success of the venture.

• A Vision - An entrepreneur doesn't just have ideas, he has a vision on how to make an idea a success - a plan for actually implementing the idea.

• Creativity - We often hear about "thinking outside the box" but as an entrepreneur, this is a particularly important concept because as an entrepreneur, you want to provide solutions beyond the ordinary ones - as an entrepreneur you strive to have extraordinary ideas.

• Intelligence - This one is a bit misleading since there are all sorts of intelligences. There's the traditional IQ intelligence which is called logical-mathematical intelligence and there's interpersonal intelligence which is the ability to interact well with others, among others. I believe that the required intelligence differs based on the industry.

• Risk taking - An entrepreneur usually has a higher risk tolerance than the average person - he takes calculated risks and this really sets him apart from the average person.

Seasons

Seasons
A season is a part of a year. In most areas of the world there are four seasons in a year: spring, summer, autumn and winter. Seasons are there because of the earth being tilted on its axis as it moves around the sun. During the different seasons that we have, the earth will lean towards the sun or away from the sun. These seasons are a reflection of how solar energy is distributed to the Earth based on its axis of rotation as well as its shape.

The four seasons is caused by the Earth’s 23.5 degree tilt from the line perpendicular to its orbit plane (toward the sun during summer). Thus, at any given time during summer or winter, one part of the planet is more directly exposed to the rays of the Sun (see the next figure).

Beam spreading
The increase in surface area over which radiation is distributed in response to a decrease of solar angle. The greater the spreading, the less intense the radiation (and vice versa).

Megacities

A megacity is usually defined as a metropolitan area with a total population in excess of ten million people. A megacity can be a single metropolitan area or two or more metropolitan areas that converge. 

In 1800, only 3% of the world's population lived in cities, a figure that rose to 47% by the end of the twentieth century. In 1950, there were 83 cities with populations exceeding one million; by 2007, this number had risen to 468. If the trend continues, the world's population as a whole will double every 45 years.

Challenges in megacities:

Megacities will have to face different challenges of social, economic and ecologic dimensions, and should develop new solutions and actions, to answer to citizens to all their needs.

• Buuildings, housing, slums
• Homelessness
• Traffic congestion
• Waste
• Urban sprawl (also known as suburban sprawl)
• Gentrification
• Environmental problems (air pollution)
• Energy
• Water

Primate city

Some countries have one city (the primate city) which, in terms of its population size and functions, dominates all other urban places. A primate city is the leading city in its country or region, disproportionately larger than any others in the urban hierarchy. 

A primate city is at least twice as large as the next largest city and more than twice as significant. 

A primate city is number one in its country in most aspects, like politics, economy, media, culture and universities.
