What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

Question: What's the benefit of starting to save for retirement as soon as you can?


Carrie Schwab: Let me give you an example. And I don’t really have the numbers memorized, but you can get gist.

There is a pretty common example that you have twin sisters and they are both 25 years old.

One sister at 25 saves $2,000 a year for 10 years until she is 35 okay, and then she stops at 35. And she just let’s that $20,000 grow until she is 65.

While her twin sister did not save that whole 10 years, she starts when she is 35 years old, at the time when her other sister quit saving, and she saves $2,000 a year for the next 30 years until she is 65 years old, which she saves a total of $60,000.

You know who ends up with more money? Sister one, who only saved $20,000 compared to her sister who saved for 30 years a total of $60,000.

Sister one, who again only saved 10 years, almost has double the amount of money of the second sister who saved more, but waited longer, waited 10 years before she started saving, that is the power of compound growth.
