Choose a place to study not associated with another activity. In choosing a regular place to study, be sure you do not select a place that you already associate with a different activity. Most people have a time limit for how long they can keep their minds on one thing. This is called attention span. Attention span changes from subject to subject, from book to book, from lecturer to lecturer, and from one time of day to another.
People experience peaks and valleys in attention span at different times of the day.
Become familiar with your attention span. Read and study during the peaks of your attention span. Avoid studying at times when you know you will be easily distracted. If you are tired or sleepy, concentration will be difficult. If you are hungry, you will find that your thoughts drift toward what you'll have to eat when you're finished.
