This is a TedX talk all about why math is important. I loved how it addresses math and anxiety in both men and women - but how empowering and impassioned Laura Overdeck was when addressing the stigmas around women and math. Being a professor at Bay Path College (all female) this one tugged at my heartstrings a little bit :)
She covers a "Life Cycle of Exposure to Math" and I think if you have any interest in being savvier with your personal finances or starting a business this is a must watch! My favorite part had to be early on when Laura talks about how some people's brains fire the same nervous response for pain when they interact with even the most basic of algebraic equations.
Math is super important and I'm not saying that you have to have advanced degrees in applied mathematics to be successful (sorry little brother :)). You do have to understand how we interact with principals of math everyday and the better you understand them, the more efficient you will be with your money and possibly your businesses money. If you are feeling inspired after this video you should definitely check out "Success After the Start-Up" to help rebuild, reinforce, and sharpen those finance skills.
