This is an insightful observation; it would be beneficial to make sharing a habit. I am reflecting on this myself.
Please refer to the initial sentence I have written. It is both perspicacious and succinct, and it is my contention that sharing should become a habit.
Individuals possess their own unique way of life and principles. In this world, one may opt to be generous or stingy, to forgive or to be angry, to share or to enjoy alone.
Each choice reveals one's personal character and attitude toward life. It is therefore unnecessary to debate the relative merits of right and wrong.
Let us return to the issue that is causing you concern today.
If you feel a genuine sense of fulfillment from sharing these learning resources with your roommates and are motivated to do so regardless of their response, I believe you will experience a profound sense of purpose and a sense of presence.
If one is compelled to share learning resources due to the actions of one's roommate or the desire to avoid losing face in the presence of the other individual, and there is no alternative but to share the resources in question, then a sense of internal resistance is likely to emerge. This phenomenon bears resemblance to the experience of children, who may feel distress when repeatedly urged by their parents to engage in specific activities, such as going to bed or completing homework, during the night. Despite the discomfort, the child may be forced to comply with the parental request.
The experience of performing an action that one does not wish to undertake is arguably the most irksome, and the sensation of being constrained is truly indescribable.
If one is adamant about not sharing, one should adhere to one's principles regardless of external pressure. However, if one is concerned about maintaining one's reputation and is unable to renege on one's commitment, then sharing is an option. It is crucial to recognize that sharing resources is a matter of affection for one's roommate. Refraining from sharing is simply a matter of obligation. One's decision is not inherently wrong, but it is important to remain composed when others treat the shared resources differently. What is shared is for the benefit of all, and how others utilize it is their prerogative. It is uneconomical to internalize the consequences of others' actions.
One might posit that a disposition to allow sunshine into one's heart would facilitate the act of sharing as a matter of course.
Furthermore, it is my sincere hope that you will mature into a perceptive and carefree young adult, with aspirations and ambitions during your formative years, and that you will not allow these qualities to be squandered.

I understand how you feel, it's frustrating when you're putting in so much effort and others aren't reciprocating. It's important to remember that everyone has their own pace and way of learning. Maybe having an open conversation with your roommates about your feelings could help bridge that gap and encourage them to engage more.
Sharing is caring, as they say, but it's also okay to set boundaries for yourself. It sounds like you're feeling a bit taken advantage of, which is totally valid. Perhaps you can suggest study sessions or goals that you all can work on together, which might motivate your roommates to be more involved and appreciative of the resources you're offering.
It's commendable that you're willing to share, but it's equally important to honor your own needs and ambitions. You've made an effort to include your roommates, but if they choose not to participate, it's not a reflection of your worth or efforts. Consider focusing on your goals and perhaps seek out likeminded peers who are as driven as you are for support and collaboration.
