Common Pitfalls

Pitfall	Problem	Fix
No emergency fund	One event = debt spiral	Build $1000 minimum before anything else
Investing before high-rate debt	Guaranteed loss vs uncertain gain	Pay >7% debt before investing
Lifestyle inflation	Income rises but savings do not	Auto-save raise before spending it
No insurance	One disability = financial ruin	DI insurance before investing
Neglecting 401k match	Leaving 100% return on table	Always capture full match first
Buying too much house	House poor — no cash for life	Keep PITI below 28% gross income
No written plan	Drift without direction	Annual financial plan review

Best Practices

• Automate everything — savings, investments, bill pay — remove willpower
• Live below your means — the only wealth-building rule that matters
• Savings rate is the lever — income matters less than what you keep
• Insurance before investing — protect downside before building upside
• Written financial plan — annual review of goals, progress, and adjustments
• Teach your children — financial literacy compounds across generations
• Net worth over income — a $50k earner who saves 30% builds more than $150k earner who saves 5%
