The sequence of returns risk is most dangerous in the first 7 years of retirement. Maintaining a 3-year bond ladder that covers basic expenses eliminates 94% of the historical sequence risk scenarios.

We implemented this strategy after reading your previous article and our savings rate went from 22% to 41% in six months.

Can you do a follow-up article about how this applies to people with variable income? Like freelancers and consultants?
