Very talented people can easily accomplish all three, especially in tech.
I guess the lucrative and secure part are supposed to be in tension? EG, if something is lucrative, there will be lots of competition that fights and eats away the security? But that same lucrativeness causes security, eg, golden hand cuffs.
Lucrative and secure are in tension only if the work is also very interesting (or fulfilling/challenging/stimulating, etc.)
If a job is all 3 of interesting, lucrative, and secure, then everyone will try to get that job, and the competition will either drive the salary down, or drive the job security down, or both.
A more general version of this rule is that anything desirable (or "scarce" if you want to use an economic term) in life will soon be pursued by others to the point where it becomes no longer desirable. That's the essence of how markets work.
The trick to wealth is to know (through some combination of vision and luck) what is going to be desirable ahead of time and obtain it before everyone else knows they want it.
In an economy with a healthy labor system, someone skilled in a certain field (say, software engineering) can just get a new (sufficiently lucrative) job if they lose the one they have, so there's no _necessary_ tension between those two.
Most people don't find software development "interesting" at all. And let's face it, the kind that pays well is usually rather boring, while the kind that is interesting usually doesn't pay very well, or at all in the case of open source.
