Work. It's a blessing and a curse but if you love what you do then it is not work. What gives you a sense of being and makes you feel like you're worth a little something. You're contributing to society whether it's flipping a hamburger or running an office job or even truck driving. Somebody's going to do it whether you're picking up cans on the side of the road or you're the it man at the local college. But to answer the question how does it fulfill you like I say I think it's more of giving you a sense of being like you're part of the crew. You're on the team to make the keeping the world spinning around. I've had many times in my life where I haven't had a job and it was cool for like a week but then you kind of go stir crazy you know. So then you get a job and then you want to be home. Again it's a blessing and a curse
