Don’t ever confuse the two, your life and your work. That’s what I have to say. The second is only a part of the first.
That’s the only advice I can give. When you leave college, there are thousands of people out there with the same degree you have; when you get a job, there will be thousands of people doing what you want to do for a living.
But you are the only person alive who has sole custody of your life. Your particular life. Your entire life. Not just your life at a desk, or your life on the bus, or in the car, or at the computer. Not just the life of your mind, but the life of your heart. Not just your bank account, but your soul.
