Part of the feelings & reasoning that went into the DiamondBack/West Arête decision
Long-term happiness on the job comes most easily where one has mastered 80% of the job at hand and is faced with about 20% new and challenging material. Mastery comes from extended practice, which is only possible with time and a mind to improve. Time and a mind to improve come from being committed to a job. (Same with a marriage.) Plus, being committed to a job in and of itself results in happiness simply because you’re not looking elsewhere.
So, it boiled down to: At which company will I have the easiest time keeping an active commitment to my post? That answer was easy: The place I’ve already helped build, the place that is familiar, the place that allows me to work from home and lets me dice my vacation time up into minutes that I can take virtually whenever I want.
