The Success of Introverts vs. Extroverts

New research from Adam Grant, the youngest tenured professor at the University of Pennsylvania’s Wharton School of Management, is really intriguing. In his study, Grant collected data from sales representatives at a software company. He began by giving reps an often-used personality assessment that measures introversion and extroversion on a 1-to-7 scale, with 1 being most introverted and 7 being most extroverted.


Then he tracked their performance over the next three months.
The introverts fared worst; they earned average revenue of $120 per hour.
The extroverts performed slightly better, pulling in $125 per hour. But neither did nearly as well as a third group: the ambiverts.
In Grant’s study, ambiverts earned average hourly revenues of $155, beating extroverts by a healthy 24 percent.

Who are Ambiverts?

Ambiverts, a term coined by social scientists in the 1920s, are people who are neither extremely introverted nor extremely extroverted. Think back to that 1-to-7 scale that Grant used. Ambiverts aren’t 1s or 2s, but they’re not 6s or 7s either. They’re 3s, 4s and 5s. They’re not quiet, but they’re not loud. They know how to assert themselves, but they’re not pushy.

Grabbing HTTP headers with Python [ 7 lines of code ]

As I mentioned in one of my previous post, I started with learning Python.

Here is one of the first scripts I wrote. It grabs the HTTP Response header. Great thing is that it’s possible to do this with only 7 lines of code.

Script code:

import urllib2
import sys
url = raw_input("Full url:")
header = urllib2.urlopen(url).info()

Example usage:

$>Full url:

As a result, you should get something like:

The story you should always keep in mind

The story

One farmer whose corn always received first prize at the local fair, used to share the best seed with all the villagers around.
When asked why, he said: It’s just a matter of interest. Wind carries pollen from one field to another. If my neighbors would grow low-quality corn, cross-pollination would reduce the quality of my corn. That’s why I always share with others the best seed I have.

The conclusion

Everything we give to others, we give to ourselves.
It is impossible to help others, and not helping ourselves in the same time.
It is also impossible to do harm to others while not doing harm to ourselves.

Lessons learned from my first 30-day challenge

Hello again!

If you didn’t see my previous post, for the last 30 days I gave myself a challenge, that I will not go to Facebook, Twitter, and social media in general, that I will minimize mails activities and try to do something more useful.

Well, my challenge was successful. Honestly, I expected it will be.

What can I say now, after this challenge:

  • You will not miss anything really important if you’re not on Facebook or Twitter – important news were getting to me in other ways
  • You will feel better without so much not-necessary information
  • You will have more time for other activities
  • You can get Twitter followers without tweeting – for one month without Twitter, I got 19 followers.


I enjoyed time without Facebook/Twitter/Social Media, and in the moments I felt like opening Facebook or Twitter, I would take a book. I started with 100$ Startup. I have read it completely, I am not so satisfied with the book itself, but more about this in other post.

After this one, I started a new book – The Gambler from Fyodor Dostoyevsky. I read this book as well, it’s a great one.


Parallel with this, I decided to take course on Python. I started with Learn Python The Hard Way, and until now, I passed more than half.
Since I “speak” more than few programming languages, learning Python is not something  hard. It’s even pretty easy. So, after I finish the course I mentioned (btw, it’s free! ), I will start with reading a new book on learning Python.

I think that 30-day challenge is a great way to motivate yourself to do things you want to do, to try something you never tried before, etc.
I will for sure give myself next 30-day challenge really soon.

30 Day challenge – Stay out of social media

Yesterday I was reading post from Matt Cutts about his last 30 day challenge, so I decided to take one as well.

For the next 30 days, I will not visit Facebook, Twitter and social media in general. Also, I will stop with reading online articles, and I’ll try to minimize my email activities. Instead, I will study and read more books.

Next blog post I will write in 30 days, and tell you about my results.

The challenge starts today at noon ( meaning, in about 40 minutes ).
