Troubleshooting Decision Tree

CopyWhich 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

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
