Build your financial foundation first
Put on your own oxygen mask before helping others.

💡 The aeroplane oxygen mask
On a plane, you're told to fit your own oxygen mask first — not because others don't matter, but because you can't help anyone if you pass out. Financially, your emergency fund and debt control are the oxygen mask. High-risk investments come only after you can breathe.
A sensible order of operations
- Budget — know where money goes. A common starting guide is 50/30/20 (needs/wants/savings), adjusted for your reality.
- Starter emergency fund — one month of essential expenses.
- Clear high-interest debt — credit cards at 30–40% a year beat almost any investment return.
- Full emergency fund — typically 3–6 months of essential expenses (more if income is irregular).
- Insurance — health and, if others depend on you, term life.
- Long-term diversified investing — retirement accounts, broad funds.
- Optional high-risk slice — if you choose crypto, a small portion you could lose entirely.
"Financial freedom" maths — with honest caveats
A popular rule of thumb says a portfolio might sustain withdrawals of about 3–4% a year. So annual expenses ÷ 0.04 gives a rough target. It's based on historical stock/bond data in specific countries, not crypto, and ignores taxes, health shocks and bad sequences of returns. Use it to frame a goal — not as a promise.
Crypto allocation questions
- Could I lose 100% of this without changing my life?
- Do I understand custody, scams and taxes for this asset?
- Is it sized so a 70–80% drop doesn't make me panic-sell?

Key takeaways
- Budget → emergency fund → kill high-interest debt → insure → invest.
- Emergency fund: 3–6 months of essentials.
- FI target ≈ expenses ÷ 4% (rough, not a promise).
- Crypto, if any, is an optional small slice.
