majiayu000 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

Fatal:
- Hourly billing instead of value-based → Capped income, commodity positioning

- 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

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 |
