Replying to this (and also to address those who are burnt out).

I have some who went into freelance tutoring or tuition centres. Pay may have decreased but workload decreased A LOT more.

If you still prefer some stability, some of my friends hopped to other Ministries or SB. I think even after 5-7 years of teaching, you'll still be considered young enough and there's still quite a high chance to be able to hop to these places.

Of course, there are also those who went to pursue their passion by starting from scratch in the private sector, or setting up their own businesses.

Many different possibilities, but one thing I noticed was that all of them were a lot happier and healthier after that
