I'm somehow at the point where I'm one of the most senior people in my team (alright, not actually usually a great sign, but it's always been very small) and pretty much unsackable. I like all my immediate coworkers. My last raise put me near the upper limit of the pay range in my location and position. My boss is a very reasonable person and one of the most effective people-handlers I've ever met. Generally, my position is low-stress, I've nearly no greys, and I can count on one hand the weekends I've worked in the last two years. 

Then I look at where my peers from both my university and high school graduating classes, and see how many times they've job-hopped, and I wonder what I'm missing out on. Moving companies - scratch that, moving FIELDS - is how you get really exciting, prestigious roles. And fat stacks, for when momma's gotta buy a new yacht. 

I'm happy where I am, and not looking to move around, but sad that I'm definitely not living up to my full (career) potential. I wonder what I could've been if I actually pushed myself rather than having coasted since I got into grad school. 

Also, I've been thinking about doing a post comparing where my elementary school and high school peers are now. I know that both groups are equally smart, but also that my high school peers self-selected to go through the discomfort of switching schools, and I wonder if that was indicative of any elevated level of risk-tasking or ambition that was only magnified over the years. I'm not sure either how I'd set up the job classification buckets to include enough diversity at a glance, but without being overclassified (overfitted?). Luckily I'm only gonna have a hundred data points from both groups combined, so it won't be too lengthy of an exercise.
