Build Projects Early and Often
According to McKinsey's AI research, employers value demonstrated skills over credentials. Start building projects within your first month of learning, even if they're simple. Your GitHub portfolio matters more than certificates.
Stay Current with Rapid Changes
AI evolves faster than traditional fields. Follow key researchers on Twitter/X, subscribe to The Batch newsletter, and regularly check arXiv.org for latest papers. The skills you learn today may need updating within months.
Don't Get Stuck in Tutorial Hell
It's easy to endlessly consume courses without building anything. After completing 2-3 foundational courses, shift focus to projects and competitions. Learning by doing accelerates skill development.
