Humans were not meant to sit in cubicles.
Humans were not meant to spend 8 hours a day working on reports and clicking aimlessly on the web to relieve the tedium.
Humans were not meant to be imprisoned by a workforce that wants you to do repetitive tasks mindlessly.
Humans are meant to be adventurous and creative, with bursts of brilliance (whether through exuberant play or hard knuckled persistence).
Children understand this. As adults we unlearn this. We are taught to work hard, conform for the good of society, buy a house, put away money into a 401K and make a stable environment for raising our kids. We are taught to be "wage slaves".
Sadly, most humans will never break free. But that makes it even more important that you become that rare exception (at least for a while). You have a duty to be brilliant, exuberant and adventurous. Laugh hard, fight injustice (aka stupidity), be creative and kind.
Be passionate. Don't be afraid to piss off people. Sometimes people need to be shook up.
Draw, paint, dance, program -- set an example for your kids. Let them know that it isn't their duty to conform, accept the status quo or "work for the weekend". The best thing you can do for your kids is to show them what it means to be free -- to be truly human. Brilliant, volatile and utterly unique. Take chances. (You don't have to quit your job to do this.) Just do something to express your joy, your uniqueness, your value as a human.
F*ck your boss. No, not that person you report to at work. Your real boss: the mental shackles that keeps you "in line". Break those shackles.
Not everyone can do this. But it is your duty to try.
Sometimes, when your boss isn't looking... let go.
