Like to hitch on this thread for advice.

Some years back, I stopped work for awhile and joined the current company, with nearly 20% paycut. I am with them for 2 years.
Work-life balance (WLB) is decent, and colleagues are fine too.
However the pay is stagnant. The company doesn’t give yearly increment and bonus is low.
I am unsure whether to seek better opportunities, and risk sacrificing WLB.
If I don’t look out now, I may be stuck with this company since I am already 40 years old.

So pay vs WLB, what do you advise? Thanks.
