When you sit down to study Torah, clear your mind and experience a feeling of total newness towards what you are about to do.  This will give you pleasure in the mitzvah of learning Torah.

Just as a young child remembers well because of the freshness of his mind when he studies, so too you will remember what you study when you master the ability to enter a fresh state of mind whenever you begin studying Torah. 

~ R’ Moshe Feinstein zt”l
