Kol Has’chalos Kashos. Just like you can’t enjoy the music from your violin when you first start taking lessons, your learning starts out as a burden.
In truth, you probably do already enjoy it in retrospect but you find it hard to get started. If this is the case you should keep reminding yourself that it does become enjoyable.
The more you can produce from your learning the more enjoyable it becomes. It can be through being Mechadesh, outlining a Sugya, sumarizing, Paskening.
And most importantly, learn what you enjoy. In your own time, don’t push yourself to learn the Yeshiva’s Masechta. Choose your Masechta or your own Limud (Nach, Ein Yaakov, Halacha, Seder Hadoros, Drush, Mussar, Machshava).
