Troubleshooting Decision Tree

code
Which path should I choose?
├─► Like visual/creative work? → Frontend
├─► Prefer logic/algorithms? → Backend
├─► Want to build complete products? → Full Stack
└─► Love automation/infrastructure? → DevOps

Stuck in tutorial hell?
├─► Stop watching, start building
├─► Pick ONE project and finish it
├─► 70% building, 30% learning
└─► Deploy something live today

Can't find a job?
├─► Portfolio too weak? → Build 3 real projects
├─► No GitHub activity? → Contribute to open source
├─► Resume weak? → Add measurable achievements
└─► No network? → Join communities, attend meetups

Common Failure Modes

SymptomRoot CauseRecovery Action
Analysis paralysisToo many optionsPick popular stack, start today
Outdated learningUsing old resourcesCheck resource date (must be 2024+)
Impostor syndromeComparing to expertsFocus on daily improvement
BurnoutToo fast, too much1-2 hours/day consistently

Validation Checklist

Before marking path complete:

  • • Can build project from scratch without tutorial
  • • Understand WHY, not just HOW
  • • Have 3+ portfolio projects deployed
  • • Can explain concepts to others
  • • Passed technical interview questions
