Here's how i'd access the situation,

- less money, no learning: leave immediately, you will feel much better.

- good money, limited learning: most of the jobs fall under this category for experienced people, use your spare time to learn new things. look out for new opportunities don't rush.

- good money, lots of learning: you must be starting out. for people with years of experience this will be momentary, enjoy while you can. look out for the next gig.

Most important thing here is never stop learning and continue to do what you enjoy most.

All the other things around: shitty management, inexperienced teams (jerks), politics, etc don't waste your energy and time unless if you have a "good" manager to work with.

first of all its hard, really hard. (at least for me)

and then when you find some time it comes at a cost.

waking up early is an option, works well for me. but the catch is you get tired easily and then in long term it affects health.

my advise is to pick things very carefully, time is very limited.
