Mental Math: Years to Double an Investment

Sharing a very simple, but handy mental math rule that was mentioned in quite a few of our MBA classes, such as Investment Styles and Strategies, Designing Financial Models that Work and others:

If you want to quickly ballpark the # of years it will approximately take for an investment to double, then just divide 72 by the annual growth rate. For example, if your investment grows 7% a year, it will take slightly more than 10 years for it to double (72/7). But if it grows 36% a year, it will only take about two years to double (72/36). 

You can read more about this “Rule of 72” on Wikipedia. Now, you now you can come across as a math genius without much effort 😉

Happiest Countries According to Studies

There are a lot of different approaches to measure happiness levels in a given country and, of course, they are all imperfect. These two recent studies seem interesting though: According to the latest Gallup, these are the happiest countries:

% Thriving in 3+ Elements of Well-being

  1. Panama 61
  2. Costa Rica 44
  3. Denmark 40
  4. Austria 39
  5. Brazil 39
  6. Uruguay 37
  7. El Salvador 37
  8. Sweden 36
  9. Guatemala 34
  10. Canada 34

And these lists are by the UC Berkeley professors, teaching “Science of Happiness” EdX MOOC:

Why Berkeley-Haas

People sometimes ask for my reasons behind choosing Berkeley-Haas among other schools.

Berkeley. Is MBA worth it

Shortly, these are the reasons:

  • Focus on technology and entrepreneurship.
  • Location, location, location. Not only because it is sunny California, but because being close to Silicon Valley opens many career opportunities that are highly germane to my vision.
  • It is a part of a larger top university.
    • For instance, I do not think I would enjoy going to LBS or INSEAD as much. These are great business schools, but these business schools are not part of larger universities.
    • There is something special about being on campus with ~30 thousand smartest students from all over the world who also major in fields other than business.
    • For example, UC Berkeley is currently top 1-2 in Computer Science, top 1-5 in Physics and top 1-3 in Mechanical Engineering.
  • Believe it or not, but the I find the defining principles personally appealing.
  • Great brand and good rankings do not hurt either
    • In particular, I liked the fact that Haas ranks well on the “Student evaluation” axis, it is #2 in “Students’ evaluation of career services” and quite high overall “Student rating of the program (out of 5)”, 4.56, according to The Economist 2013 rankings.
  • I really want to add “people” to this list of Berkley-Haas strengths, but this would be probably unfair as I cannot compare to other schools as I could not know it for sure before starting the program.

The list could go on and on and on, but these are probably the main ones top-of-mind. Of course, there are drawbacks as well, but no one schools is perfect.

Let me know what you think!

Italy and a little bit of France

It’s been more than seven months already and I finally found some time to blog about our Italy and France honeymoon trip in May, 2013.

We wanted to see many things, but didn’t want to spend the entire holiday in a car, so we tried to leave some time to chill. This resulted in the following plan:

Rome and Vatican → San Marino → Bologna → Florence → Cinque Terre  – Riomaggiore → Monaco / Menton → Nice.
