Another bit to consider: It took a long time to realize that basically everyone wants basically everyone to succeed, as long as incentives align. It was very easy to imagine I was swimming upstream early in my career - especially my early mentors urging me to specialize to find success. My initial temptation was to "specialize" in hot/attractive topics in an effort to be the "indispensable X authority". But my PhD advisor urged me to "not swim in red water", where the incentives are inherently conflicting - everyone wants to be "the X person".
Much better to find a team working on a good problem somewhat like the ones you want to solve and just push along with them. You can save yourself a lot of energy by slotting yourself into a system that aligns with your preferred direction of travel, even if only a little bit. The current carries you.
Seemed like everyone was doing topics in the “red water” and felt useless to not.
I found my areas of interest were the “red water” of 20 years prior and there was little left and it didn’t solve problems relevant to industry.
Quit PhD and got a job where I was grossly underpaid until the next one.
The amount of people I've heard of say they want to go into email security is very small.
Also, while the original advice about “vision” sounds reasonable, it also sounds a bit dogmatic. The filpside of “career vision” is “tunnel vision”. And life is not deterministic, it has a much more probabalistic nature. Hence, curiosity and open mind.
Things change fast in our industry so being able to pivot to something nearby is paramount for maintaining a career in this field.
Not everyone has the fortune to spend 15 years at a FAANG or other large corporation. Sometimes you have to build it.
It's the same as what you do, except I need the reminder...
I think there are certain things that are not likely to change, and must be aimed for. For starters, being healthy, proactively working towards a retirement nest egg, so that you don't end up homeless and starving in case things go south too fast.
There are many such things I hold as things I would want several years from now. Good health, free time and enough money to not need a job to just put food on the table, and a roof above my head.
Sound like the utility function for a lot of people I would say.
