Troubleshooting Decision Tree

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

| Symptom | Root Cause | Recovery Action | |---------|------------|-----------------| | Analysis paralysis | Too many options | Pick popular stack, start today | | Outdated learning | Using old resources | Check resource date (must be 2024+) | | Impostor syndrome | Comparing to experts | Focus on daily improvement | | Burnout | Too fast, too much | 1-2 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
