How do you constantly improve your pay / career in the tech world?

[BrilloPad]

Get more specialised.
Find a niche.
Budget 2K or more a year for training. And budget time for training, too (this is the hardest part).
Improve your maths to university level, if you can.
Every 10 years take a sabbatical and do a rigorous and deep course of training in something you like.

And most importantly, do what you enjoy and the money will follow. Not the other way round.

GCSE Maths is a piece of piss.

That's kinda the point of computers, they always have been supposed to do the predictable stuff. Nothing new there.
