I read that book this year. The entire book can be summarised as.

Don't attempt to beat the market. The market cannot be beat (many examples in the book). Invest in index funds long term which is the right mix of risk/reward for most people.

It does have a chart in the back which tracks your age and situation. For example as you approach retirement you should start to liquidate your funds and buy government bonds so you aren't hit by a bad year when you have to start drawing on your investments.

It did convince me. I opened accounts with Wealthsimple and Questrade the next day.

A great site for fellow Canadians is http://canadiancouchpotato.com/ - you can skip the book.

Ramit Sethi's I Will Teach You to be Rich is the personal finance book that introduced me to all the basics (e.g., paying off debts, how credit scores work, why not investing in index funds across diverse asset classes is moronic, etc.).

Dead practical advice despite the somewhat sleazy writing style (see title of book).
