Dissatisfied with the new building as there are now other options

Then there is probably still a cook (m/f/d) missing and/or someone for the shopping ... :)

I like to cook myself and I have a man for shopping :p

Tell me.
Honestly, no. That dream of an earlier retirement age is not for me. I am really too young for that, my job is fun and also a purpose in life. If it is so important to you, reduce now instead of saving, so that you can leave earlier in 20 years

I see it the same way.
The oft-cited early retirement or life without work is seen as a path to happiness, similar to emigrating to a finally great country.... The person who leads an unhappy life during their working years will not be different in retirement if they do not CHANGE THEMSELVES. The neighbor’s garden is always greener...
I once read about an illness or suffering pattern in even younger people that arises from craving the relieving retirement almost as a hope for salvation. But what do you do then after the third cup of coffee, after the 10th documentary, etc.? For me, there is hardly anything better than having a meaningful activity lifelong. You just have to manage to separate your own satisfaction from the topic of money; but that rarely succeeds... in the background, the calculator keeps ticking.
What surprises me is that the improvement of quality of life often goes hand in hand with new purchases or being free from work, but rarely with a change in one’s own lifestyle toward more time and less need for money.
– my full agreement. There is a book where countless older or also dying people were asked what they would do differently "next time." It was exclusively things in the area of interpersonal relationships, never a kitchen or car; exactly such things were excluded and looked back on with bittersweet amusement.

I know retirees who have built a new purpose in life during early retirement and are happier/more satisfied with it.

That exists and it is also great when you take a new direction that you maybe could not live before. But the rule does not seem to be that if I look around among my peers; I hear a lot more complaining.

...

Then these people have (not yet) found a fulfilling purpose in life and perhaps will never find it.

...
However, this does not seem to be the rule to me when I look around among my peers, I rather hear a lot of complaining.

See above.
Of course, it can also be a challenge to spend retirement every day with your spouse.

All in all: If someone (m/f/d) sees their life's purpose in leaving regular work life as late as possible, they should feel free to do so. However, there are certainly enough employees who (would) gladly pursue other goals they consider more meaningful. Not a few employers support this.
Certainly, there are also enough who simply do not know what to do with themselves.

One could also think, for example, of early retirement.

Sorry, but that is really a textbook male comment. The OP managed, after the parental leave, not only to avoid the "mom trap," but also to continue her career, and that too in self-chosen part-time. Now that’s what I call a hat trick. A six with the bonus number, Hans Rosenthal would make his "Great!" jump :)

One (hat trick) does not exclude the other (early retirement) at all. Who knows how one will think about life content in 20 or 30 years? By the way, my wife also managed the hat trick and I shouted/jumped "Great!" ... :)

The original poster managed, after the parental break, not only to avoid falling into the mom trap but to continue her career, and that even in self-chosen part-time. I call that a hat trick. A double six with an extra number, Hans Rosenthal would do his "Great!" jump :)

In general, early retirement is certainly a nice thing for some. At the moment, I am probably still far too young to think about that. My plan would rather be to continue our current model with 2x part-time in the long term. That would be a real gain for me in 10-15 years (so in my mid-40s to 50s), to work part-time with children who are more independent or even fledged. And then also together with my partner. We will see if we can enforce that or if we will come under pressure with older children.
