Yesterday I walked on campus and noticed a friend who I didn't see in a while.
Why is that something that bothers you?
I got a lot on my back and the only time I have to myself is on Saturday.
It's nice to see a friend you haven't seen in a while, I do understand having a busy schedule. I'd recommend trying to find some time to set aside just for a simple hello.
I don't have time to talk to anyone else at this moment. I'm trying to accomplish as much as I can everyday and I don't want to stop.
While it's great that you are setting your goals high, don't you think you still want to enjoy that leisure and maintain relationships? Relationships  a healthy part of a work-life balance, so why don't you try hitting up that friend and see where it goes?
