Have you ever had a real job? You can of course express yourself in your work, but professionals get paid to serve others, not themselves. You may think that's an idiotic opinion, but join us here in reality and you may change your mind.
I try to make my IVs look beautiful and professional when I start them on patients. But ultimately, I'm being paid to start one that works and doesn't cause them more harm. They don't pay me to just do whatever I want without regard for what anyone else thinks. That's a hobby, not a profession.
This post applies to every professional (including me in healthcare). Egotistical software developers just happened to be on my mind when I wrote it.
