You don't have to want to do something to do it. Acknowledge that you don't want to study but go ahead and do it anyway.
If you find it roughly impossible to study no matter how hard you try, look into ADD/ADHD. I have had that problem all of my life but I didn't get diagnosed until my early thirties when I had already flunked out of seminary. Medication made two worlds of difference in my life. It was like the world went from black and white to color or from two dimensions into three.
If you find you really can't study there may be more going on than laziness. Check out the book "You mean I'm not lazy stupid or crazy?"
