Elena manages a long-term process for families who would rather be right over decades than interesting over weekends. She writes about temperament, costs, and the difference between a thesis and a mood. 31 Experts selected her because she can talk about markets without recruiting the reader into a casino.
Elena VossThe 30 Insights
Write the sell rule first
Mood is not a policy.
Count the costs
Fees are a performance drag with excellent manners.
Calendar, not headline
Rebalancing is a date.
Size so you need not be clever
Cleverness is a scarce resource. Do not spend it on survival.
Rules for silence
If the policy is quiet, you can be too.
The Top 10
Inside this Special Edition, Expert #31 answers these ten questions. That interview is one of the most valuable parts of the book — so the answers stay in the book.
If you could give just one piece of advice to someone starting out in this discipline, what would it be?
What was the biggest challenge you faced in your career, and how did you overcome it?
What is the most important “Never do this…” rule in your discipline?
Who inspired or mentored you, and what did you learn from them?
What is the biggest discovery you wish you had known on day one?
What do outsiders consistently misunderstand about your discipline?
What decision looked small at the time but changed everything?
What skill outside your discipline has contributed most to your success?
What belief did you hold when you started that you no longer believe today?
When your career is remembered, what do you hope people say you stood for?
We show the questions so you know what you will find inside. We do not publish the answers here.
What readers will learn
- How to write sell rules before you buy.
- How to treat costs as a first-class decision.
- How to schedule rebalancing away from headlines.
