Studying the stock market is difficult, slow, and complicated; you'll end up with a headache sooner or later. Each company is a world and a new situation; accounting has many interpretations... If you get overwhelmed along the way, leave it for a month or two and come back calmly. I even stopped studying completely for 8 months because I was so overwhelmed.

It's better to go slowly and consolidate knowledge than to go fast and be poorly focused.
