I read some posts here, and I’m not even 40, but I feel like I already have the mindset of a 50-year-old, lol.

True what? Why change a system that has been running well w/o any major issues for many years? Why go through another learning curve just to adapt to a new framework for the sake of "keeping up with the latest tech"?

Anyway TS, good luck finding new job.
Most people I know, by 40+, already want to settle down in their current company.
Some, with high ambition (tambah biini, lol), will go all out jilat upper management so they can spend their last few years at the company at the higher management level.
