Graduate school is hard. Make it easier by setting boundaries. Boundaries are drawing a line in the sand, the difference between saying yes and no. They will let you know who your real friends and family are. Setting boundaries isn’t being petty, its knowing your limits cause people will take as much as they can. Although you may not be able to hang out with family and friends when you want to and do the hustle. Still, do your research and fulfill those professional duties and go home. Have fun, but do what you need to do to make yourself feel good.
