It's the period where you need to quickly learn you're not the centre of the universe and nothing will be handed to you unless you go and get it. You're not exceptional or irreplaceable unless you go out of your way to prove it to complete strangers with your skills and knowledge. These first jobs you take will often define your future jobs and social status.

There will be people who'll tell you now's the time to live and later's the time for slaving away in a boring job you hate. I say the opposite. Now's the time to study and hone your skills and become desirable for employers. That way, you stand a much better chance of landing a job you actually like and life you will enjoy living.
