late night musings

How do i put this? To be frank, I think that I have sacrificed too much time and opportunities on my behalf for others ever since university started. For most of the time, I made these choices for my own benefit but now i can see that this "sacrificing" is not worth the effort anymore. I don't know why i had to miss so many opportunities when the other person/people did not even consider doing the same or think they needed to.
