work is going to kill me eventually

so i have been at work every day for a minimum of 6 hours since march 31st, and right now I really want a day off. Its like I'm a workaholic, i have a hard time saying no to my boss if they call me in to take someones shift. I think at times i can be far too nice, and i think people will take advantage of that. Its a problem that i have a feeling that i will always have, i really could care less about benefiting my own situation in most cases as long as i can help out. Its like the discussion i had with Dan the other day, we have respect for people that help people out because they earnestly want to, the ones that do good so they feel good. I kinda just go to work to help out other people because it gives me that feel good feeling. so because of that "feel good" feeling i have been here pretty much 9 days in a row and i still have to work Thursday, Friday, Saturday, and Sunday morning. Pretty much i just work a ton but I'll do things for others before i do anything for myself, I'm just not very selfish i guess, well at least that is how i feel i could be wrong. well on other news i got an A- on my paper on Buddhism which is chill, that wasn't a hard paper to write and my teacher thought i came to a few interesting but valid conclusions. well I'm just going to sit here for another 2 hours and 40 minutes. i really hope that i don't get called in today 60 hours is enough for this week, 72 is just approaching the point of ridiculousness.
