Net Worth Tracker + Reading Log + Fatherhood Planner. Three logs that look unrelated until you read them ten years from now and notice they are, all three, records of the same thing: the slow accumulation of the wealth that compounds. Financial capital. Intellectual capital. Family capital. None of these compound from a single decision. They compound from many small inputs over many years, and the only way to know they're compounding is to record them — because the felt experience of compounding is non-existent in any given week, and the multi-year picture only becomes visible from the data.
This post is the argument for treating all three as the same kind of work. Net worth is one form of wealth. Reading is another. Family is the third — and the framing that family compounds is the framing that produces the practice of explicitly investing in it, rather than assuming it will take care of itself while the working week consumes the attention.
The Net Worth Tracker · financial capital
The Net Worth Tracker is the simplest of the three. One page per month. Assets in one column, liabilities in another, net worth at the bottom. Tracked monthly, reviewed quarterly, summarised annually. That's it.
The discipline isn't the calculation — that's trivial. The discipline is the monthly cadence. Most people calculate net worth twice in their life: once when they apply for a mortgage, once during a divorce. Neither calculation produces a curve. A net worth that's recorded twelve times a year produces a curve. The curve is what's useful.
What the curve shows over time:
- The savings rate as it actually is, not as you imagine it. Most people overestimate their savings rate; the monthly data corrects this.
- The impact of major decisions. The decision to take the higher-paying job that requires more spending on commuting. The decision to buy the larger house. The decision to take the parental leave. Each of these shows up in the curve months later.
- The accumulation of small inputs. The 5% pension contribution that produces a noticeable line by year three. The small monthly investment that becomes a substantial holding by year five.
The Net Worth Tracker is not a budgeting tool. It is a long-horizon record. Budgeting is a different practice; the Tracker assumes you have one (or that you don't, and the Tracker will make the absence visible).
The Reading Log · intellectual capital
The Reading Log tracks what you've actually read, not what you've started. Title, author, date completed, one-sentence summary, and a 1-5 score for whether you'd recommend it. Nothing more.
The discipline is the completion. The temptation, with reading logs, is to count books-started. The Reading Log counts books-finished. The asymmetry matters — a book finished produces a different kind of intellectual capital than a book started and abandoned. Finishing is the discipline that produces the accumulation.
What the log shows over years:
- The actual reading rate. Most people overestimate this dramatically. A serious reader finishes about 30 books a year; a very serious reader, 50; the absolute outliers, 100. If your log shows 8 books a year, your reading is not as serious as you'd assumed.
- The genre distribution. Are you reading widely or in a narrow range? The log makes this visible. Three years of fiction-only, or technology-only, or business-only — patterns that aren't visible from inside any single year.
- The books worth re-reading. The 4-5 scored entries form a personal canon — the small number of books that meaningfully changed your thinking. Worth re-reading every five to ten years.
The Fatherhood Planner · family capital
This is the one that needs the most explanation, because the framing of "family as wealth that compounds" is unfamiliar in most productivity content. The framing is meant literally. A relationship with a child that has been actively invested in over twenty years is qualitatively different from one that has been passively maintained. The investment compounds. The data on adult outcomes for children whose fathers were genuinely engaged across childhood is unambiguous; the data on the relationship quality with adult children whose fathers were emotionally absent is also unambiguous.
The Fatherhood Planner is the artefact for treating this investment as deliberate rather than incidental. Twenty-eight pages, used in three modes:
- Annual. Per-child reflection — what's the developmental stage, what does this child currently need from me, what's the next year's specific investment look like.
- Weekly. One-page Sunday check-in — how much actual one-to-one time happened this week with each child, what's planned for next week.
- Memory. A running log of moments worth remembering. Specific things said, things done, small developmental milestones. Not a baby book — a working log for the years when memories blur into one undifferentiated period of being-a-parent.
The Fatherhood Planner is the most demanding of the three Compound Series 02 tools because the investment it tracks is the most emotionally significant. It is also the most valuable.
Financial capital. Intellectual capital. Family capital.
The Net Worth Tracker (£4.99), Reading Log (£3.99), and Fatherhood Planner (£5.99) handle three domains that compound across decades. Inside the Groundwork OS, the three feed a single long-horizon dashboard — the Pattern Dashboard shows financial trajectory, reading completion, and family-investment streaks as one connected view. Worth more than the working week's data because it captures the slow accumulation that matters across a life. £19.99 for the OS, £54.99 for the complete bundle with every format.

The test for whether any of these logs is worth keeping: will you want to read it ten years from now?
For the Net Worth Tracker, the answer is clearly yes. The 120 monthly entries showing the curve from age 35 to age 45 are a record that nothing else can substitute for. For the Reading Log, the answer is also yes — the 300 entries showing what you read across those ten years, with your scores and notes, become a personal canon. For the Fatherhood Planner, the answer is unambiguously yes — the memory log alone is worth more than the time it took to write.
None of these logs feel important in any given week. All three feel important when read back across ten years. The compound effect is what makes the practice worth doing in spite of the short-term tedium.
The honest next step
Pick the one that's currently weakest. If you don't know your net worth to within £5,000, start with the Net Worth Tracker (£4.99). If your reading has been narrow or thin, start with the Reading Log (£3.99). If you have children and the relationships have been on autopilot, start with the Fatherhood Planner (£5.99).
The complete Groundwork bundle at £54.99 includes all three plus the rest of the 28-tool ecosystem. The Groundwork OS at £19.99 runs all three logs inside a connected Notion workspace where the data feeds the long-horizon dashboard.
The wealth that compounds. Three logs. Read them in ten years and you'll wish you'd started today.
