Just as QQ turns out to be the unexpected cornerstone of my entire career, weight turns out to be the surprise keystone of my wellness.

Lesser examples

• rental passive incomes have accumulated into a huge cornerstone of my ffree state of mind.
• Beijing property has grown into a surprise capstone of my portfolio
• Java (I didn’t say “core-java”) and U.S. turn out to be unexpected keystones of my career longevity

For all of these, I only realized their importance after many years.

Note the words I chose. I prefer more specific tails that wag the dogs — 四两拨千斤

• I chose “QQ” not IV, because “interview” is too broad. I didn’t choose “tech skill”.
• I chose “weight” not diet not nutrition not fasting not calorie-restriction.
