It’s helpful to remember the school needs you more than you need that job. Few people are willing to do what you do.
And this is more true now than in many decades. You are a commodity, so don't let your admin feel like you have to be giving 1000% into every taks and request. Schools will ask you give until you have absolutely nothing for your family or your students.
Setting limits is key. In many positions, working longer hours strategically in the first few years can allow you to build up lessons and resources that you can reuse indefinitely. Put more time into those tasks that will pay dividends in the future, and less into things that can be done to a lesser level because they only need to be done once.
I saw a teacher give more than 10 years to our school, and she was the type who worked hours after school every night and each weekend. She got ill mid-year (related to excessive stress and burnout) and decided to retire and it was literally a BLIP on the radar of this year. No card, no big goodbye, no kind words. She was gone, and they hired someone else, and now her name never comes up. Do a good job because you care about your work, but never forget that it is JUST a job.
