Scenario A: You block out a few hours, sit down with the best intentions and try to cover everything at once: grammar, vocabulary, pronunciation. After an hour or so, your concentration drops, your head feels full and most of what you studied fades by the next day.
Scenario B: You spend 10–15 minutes a day on one clear, focused lesson. Something practical. Something you can use straight away. Each day builds gently on the last, and over time, your confidence grows without you feeling exhausted or overwhelmed.
