Day 02
✓ Completed
October 7, 2025
First real productive day in 5 years! Stopped the tutorial loop and started solving problems - completed 30 C++ I/O questions in one sitting. Key insight: spend 70% time solving, 30% learning theory. Mastered iomanip & cmath libraries. Started following Love Babbar's DSA & Striver's A2Z sheets. The separation line: once you master arrays, you're 90% ahead of most beginners. Building my question library for easy access. 🚀

Day 01
✓ Completed
October 6, 2025
Started with brain fog but pushed through. Revisited DSA fundamentals - problem-solving approaches, C++ basics, data types, operators, and memory concepts. Key lesson: rebuild the foundation instead of waiting for the "perfect mood." Made short revision notes to avoid tutorial hell. Next: conditionals & loops! 💪
