Rookie Mistakes
Common mistakes by business type that delay revenue or kill businesses.
Universal Fatal Mistakes
Mistake Why Fatal Instead
Building before validating Months wasted on unwanted product Pre-sell or LOIs first
Underpricing Can't sustain business Start high, discount later
No niche focus Can't compete with anyone Dominate one segment first
Perfecting before launching Never launch Ship MVP, iterate
Ignoring unit economics Lose money on every sale Know CAC < LTV from day 1
Universal Time Wasters
Mistake Time Lost Instead
Logo/branding first 2-4 weeks Use Canva, good enough
Custom website 3-6 weeks Use Carrd, Webflow template
Fancy tools 1-2 weeks setup Spreadsheet + free tools
Social media posting 10+ hrs/week Direct outreach to buyers
Networking events Days Cold outreach to ICP
By Business Type
Consulting/Services
Fatal:
-
Hourly billing instead of value-based → Capped income, commodity positioning
-
No scope boundaries → Scope creep destroys margins
-
One big client → Vulnerable to churn
Expensive:
-
Expensive office → Work from home/cowork
-
Hiring too early → Stay solo to $200K+
Time wasters:
-
Long proposals → One-page with call
-
Unpaid strategy sessions → Paid discovery calls
SaaS/Software
Fatal:
-
Building for 6+ months before launch → Ship in 6 weeks or less
-
Feature parity with competitors → Unique wedge feature only
-
No activation metrics → Users sign up but never return
Expensive:
-
Overbuilt infrastructure → Start on Heroku/Vercel
-
Paid ads before PMF → Manual sales first

-
Perfect design → Functional first

Recovery Patterns
If already made the mistake:
Mistake Recovery
Built wrong thing Pivot to what users actually use
Underpriced Grandfather old, new price forward
Wrong niche Double down on best segment
One big client Immediately prospect for 2-3 more
Hired too fast Cut fast, don't delay
