I'm 32 and both of my parents retired when I was a toddler, so I pretty much never saw them work (the only exception is that my dad had an art gallery passion project for a year or two.)
If your kids are like me, they will start life with a natural inclination towards achievement, hard work, and common sense. It will be in their genes since that's how you retired early.
They will like excelling at work, but they won't like sucking up to the boss or pretending to look busy (afterall, they never saw you do a thing like that, even though you did tell them you once had to). They will understand what is a healthy balance between work and leisure, since they have seen you pursue hobbies and be active in retirement.
If they are a millennial, they will search for a job that they love and hopefully also pays them well. Their goal will be to work in said job until they're 65, and enjoy a standard of living where they spend most of what they earn for the rest of their life. Their parents might not be working, but the whole rest of society tells them their career will define their life. Their parents are a pleasant aberration. They are really glad you didn't work because they got to spend so much time with you growing up and you were barely ever stressed or grumpy around them since you didn't have a job! It was the best part of their lives so far.
It *will* be especially excruciating for them when their boss or coworker is a pain, since they see that mom and dad don't have to put up with that anymore. If they feel they have some sort of safety net due to your wealth, they will be a tad bolder at work than their coworkers are. They will be the one person to advocate occasional work from home days (pre-covid) and they will sometimes be honest when they think the boss's ideas are bad, since they are not super scared of losing their job (they know they can sleep on your couch if they had to, but they never expect to actually need to). Their coworkers will email them afterwards to say thank you for saying something.
When they are really sick of their well paying job, they will complain to you about it and hope that you say they can quit, THEN look for a new job, but you never will. You will always tell them to get another job before you quit, and they always will, since they respect you, want your blessing, and know you are probably right, even though it really sucks.
They will go from job to job, getting raises every time, and eventually realize that working in general sucks and it wasn't just that they were unlucky over and over again. They'll then find a job where they mostly love the actual work, but the stress, repetitiveness, deadlines and inauthenticity will kill their motivation. They will still work hard, but they'll realize they are working for money and they will give up trying to work for love.
Only then, will they realize the true value of money. Thanks to this realization, they will no longer spend waste their money. They will start reading MMM, buy less and be happier planning their early retirement.
What's my advice? Teach your kid that working in itself is great, but working for money sucks (but they still have to do it). They will have low expectations, which might possibly lead them to liking their job more. They will also understand the value of money more since they won't be expecting to find this job they love, which would essentially mean they would work for free. If they are working for money their entire life, they will likely prefer to save more of it, so they don't have to work as long.
