Busting your ass for your current job will never be better than expending the same amount of energy finding a better job.

Are you content with your current job and getting good pay, good benefits, normal promotions/raises etc. while performing a reasonable workload? Great, keep it up. If you have extra time and energy, focus on self-improvement, family, hobbies, etc.

Are you feeling underpaid, under-appreciated, or generally unhappy with your job? Are you in a position where you can maintain your health and sanity while working harder to improve things? Great, keep working just hard enough not to get fired, and pour all of your extra time and energy into finding a better job. Never give it to your current job.

Loyalty to the company is an outdated idea. Dont let some out-of-touch CEO sell you on that bullshit. The way to improve your situation is to job hop. There’s no shame in it. Expect to do it several times before you really figure out where you want to be.
