The book The Call of the Wild, by Jack London, has as its theme the concept of "survival of the fittest". Survival of the fittest is an expression connected to Charles Darwin's theory of evolution. Organisms which are able to adapt to the environment survive. Those which are not end up extinct.
That is precisely what happens in the story by London. The main character is a dog, Buck. Buck is stolen from a family with whom he lived a comfortable life. He has to adapt to a whole new environment and conditions as a sled-dog. He turns out to be so adaptable that he becomes the leader of a pack of wolves by the end of the story.

I guess that all you have to do is focus, don't procrastinate. Shut off anything that might distract you, like put away your phone. Don't even listen to music, because sometimes that just breaks concentration. Considering how you've been trying to study for the past 2 hours, try taking a break. And continue to take short breaks so you don't get too tired!
I hope this helped haha! I've had far too much experience with the same issue.
