Increasingly, the key is to main orthogonality towards your problem solving (like an eagle) within the decaying confines of a semi-bloated (often mostly educational in terms of what not to do) ecosystem.

Which means rewriting crufty pieces of your stack when certain thresholds occur. 'There will come a point where the accumulated complexity of our existing systems is greater than the complexity of creating a new one' -- is something that happens in motion, iteratively, and which you do when you have time at all levels of the evolution that we call development.

Anyway, that's my two cents. Nice others are on the same wavelength, I think.
