 Learning data science can feel exciting and overwhelming. There’s Python, machine learning, statistics, tools, algorithms… whew. When I started my own journey, I made a few mistakes that slowed me down  and I want to help you avoid them. Mistake #1: Trying to Learn Everything at Once “Should I start with Python or Excel? Do I need to learn SQL too? What about AI?”  Truth: You don’t need to know everything right away. Trying to learn it all at once will only burn you out. What to do instead: Pick one area (like Python or Excel) and focus on it for a few weeks. Progress comes from consistency, not chaos. Mistake #2: Skipping the Basics Some people jump straight into machine learning tutorials... But haven’t even mastered variables or loops in Python! Start small, build strong. Learn to walk before running with algorithms. Trust me — the basics will serve you again and again. Mistake #3: Comparing Yourself to Others “She built a dashboard in a week. I can...
