Why structured learning beats random exploration
Random learning feels productive because you are always picking up something new. Structured learning produces results because each step builds on the last. Engineers who follow a roadmap like this typically become job-ready in four to six months. Those who jump between topics often spend a year without making meaningful progress.
Start at Step 1 regardless of your background. Even if you have some SQL experience, spending a week on the fundamentals ensures there are no gaps. The time spent is almost always recovered later when concepts click faster.
