So the question became, how do I keep tutoring and help more people, a.k.a., clone myself. I got my answer teaching a team in Bangalore, India about pension plans. I built Excel spreadsheets with formulas. But, I added one twist…next to the number cells, I added comments with step-by-step math to explain actuarial formulas and life expectancies.
The team in Bangalore loved it, it cut their learning curve down significantly. So the lightbulb went on…why can’t I build a program/website to tutor in math. Essentially, can’t I put my brain on a website. This way, people can use the calculators without me having to be there.
