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

Time wasters:

  • Perfect design → Functional first
  • Supporting every browser/platform → Chrome only initially

E-commerce

Fatal:

  • Large inventory before validation → Dropship or small batch first
  • Competing on price with Amazon → Unique products only
  • No repeat purchase strategy → Consumables or loyalty

Expensive:

  • Paid traffic before funnel optimization → Organic/influencer first
  • Expensive photography → iPhone + good lighting

Time wasters:

  • 100 SKUs at launch → Start with 5-10 heroes
  • Complex fulfillment → Use 3PL from day 1

Agency

Fatal:

  • Taking any client → ICP focus from day 1
  • Billing hourly → Productized services
  • No referral system → Build in from start

Expensive:

  • Hiring before systems → Document before delegating
  • Expensive tools → Free tiers exist

Time wasters:

  • Custom everything → Templatize deliverables
  • Long sales cycles → Productize to shorten

Local Services

Fatal:

  • No reviews strategy → Ask every customer
  • Underpricing to compete → Compete on quality/service
  • No recurring revenue → Maintenance plans

Expensive:

  • Vehicle wraps too early → Magnetic signs
  • Prime location → Start home-based

Time wasters:

  • Broad service area → Dense local focus
  • All services at once → Master one 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 |
