Anyone here feel bored working after 30s/40s?
Not that excited or passionate after working for over 15+ years.
Not the same as back in the 20s where everything seems fresh and new, and earning money is exciting.

At the same time, blessed that I still have a job given that there's a lot of retrenchment out there.

So question here is how do you guys keep yourself passionate, keen and all excited?
Do you set yourself a further goal? What goals do you set?
Have you thought about starting own business instead?

Seems like you need a break. Take a couple weeks off traveling to place that is in your to go list. Turn off work emails, get your mind off the grid.

Pursuing postgraduate depends on what you want to achieve.. you can work and take part time MBA or other post grad course, that might spark you.

Also suggest to leave toxic work environment, it's not good for long term health. Try interviewing everywhere you can.
