Only when you start working you'll understand a few things:
1. Holiday is mighty precious. In fact it's probably the major thing you look forward to each day.
2. Your wage. Just the thought of it keeps you going... Proving what you're doing actually makes sense.
3. Bureaucracy. It beats the shit out of you.
4. Self-improvement equals to a good night's sleep.
5. Colleagues. Everyone is talking in jargon (mostly), which you too, will jump onto the bandwagon later on... and years to come.
