Step 1: Define one clear goal
"Study physics" is vague. "Solve ten problems on motion" is focusable.
Step 2: Prepare your space
Clear the desk, keep what you need nearby and put your phone in another room or on silent.
Step 3: Work in time blocks
Set a timer for a focused block, then take a short break. Repeat.
Step 4: Take real breaks
Stand up, stretch, drink water. Scrolling social media is not a break for your brain.
Step 5: Reflect at the end
Note what distracted you and adjust tomorrow's plan.
When focus keeps slipping
Persistent difficulty concentrating can relate to stress, sleep or a mismatch between you and what you are studying. Talking it through with a parent, teacher or mentor can help find the cause.
