Yes agreed. I did have regret pursued my last master in climate modelling but after received a decent job with right career path. I actually grateful. Thanks to my supervisor Dr Liew Ju Neng & my science lab colleagues.
Eventho my recent job have nothing to do with my last master degree but i could say in subtle way it did have everything to do with it like;
1. The exposure in coding world
2. The exposure in math/physic modelling
3. The maturity & critical thinking i have established
