You go to school, and fill your brain with all this 'cool' knowledge. You're so smart!
Then you find a job and help save the world. Yes, you are helping people during their worst times and that's all good. Sure, it's hard work, but it's good work, you think. Oh, it's a rush man. You see things that most people will never see. Good and bad. It's life changing for sure. In the mean time, little by little, you give a little bit of yourself to the 'Machine'. Day by day the 'Machine' sucks a little life out of you until eventually you can't give anymore. Meanwhile the Machine keeps asking for more. Oh, can't you just stay 4 more hours? Can't you come in on Saturday? Then you find yourself making the calls, begging, pleading.
It doesn't matter who you are, the Machine will chew you up and spit you out. The Machine always wins.
So, get your kicks, nothing wrong with that. However, have a backup plan in case you need to bail, or are forced to bail. MAKE SURE YOU HAVE A BACKUP PLAN.
