I have this philosophy and I have to give credit to my mom since I first heard it from her. Basically it's simple: Give when you can, so that when you can't you never feel guilty.
I love giving of myself, my time, my money, my energy, my advice pretty much anything I have of value I am willing to share. Lately though I haven't had much to give. Graduating from college is a lot less fun when you don't have a job. So I'm realizing just how much of my identity is grounded in my ability to give. Not only that but also in my reluctance to take.
I really am struggling being on the other side of the table.
