In the relationship between classmates, everyone wants to be better and better than others. This is a common psychology, not to mention the scheming.
Hard work is a personal matter, and the fruits of hard work are also enjoyed by individuals. Roommates go to the library to study because people are self-motivated and want to work hard. It's normal for them not to tell you. They have no obligation.
If you want to go to the library by yourself, you don't have to ask. I don't want to go to the library, I won't go until I'm called, and I'm in no mood to read.
Effort itself is personal self-control. The result is that you don't have the self-control and can't blame others at all. Ask yourself, even if your roommate calls you every time he goes to the library, will you really go? It's easy to deceive others, but don't deceive yourself.
Don't blame your roommate for his scheming, he just doesn't want to sink like you. You think it's unusual for roommates to go to the library to read books, which shows that you both have decadent lives.
Now my roommate has begun to change, and he doesn't want to be as decadent as you. How can this be said to be scheming? You don't want to study yourself, but blame others. You can motivate yourself, but you can't stop others from motivating themselves.
The library is a public place. Whoever wants to go can go. No one forces you to go, and no one has an obligation to urge you to go. Don't take yourself too seriously You're just roommates.
There may always be some people in life who like to attribute their incompetence to the help of others. But in our life, we can't always expect others to help us.
If you want to make progress, work hard, no matter what others do. Your own efforts are enough.
