Sure! I gathered a lot of palaces quite quickly, and this was how I did it:
I went through my life inside and outside upside and down by different ways of trying.
First I went through it kind of time-wise. I made palaces for all of the schools I’ve studied in and houses I’ve lived in.
Then all of the friends that I’ve ever been to makes for POSSIBLE mmp:s, but most of them were not good as I hadn’t really been around the whole house nor really remembered enough. So mainly the better friends. The friends I also went through class-wise to begin with.
Then came all of the hobbies… Doesn’t matter what, chess, different sports, etc, club houses, home pitch, away pitch, etc… I really got creative with this one, and I think that there are still a lot to be done. I even made jotted down some video games and computer games, of which I’ve used only one.
Familly… Grand parents, aunts, cousines, etc.
Vacations: Does the family have a vacation house? Can you remember any of the hotels or other buildings you’ve been in while travelling good enough?
What about subway stations? Restaurants? work places that you’ve worked on? In the meantime, with each of these things, there might be something other popping up, for example maybe you have a work place, but not only that… the travell there can make a great journey, and another company that you used to visit with that work can make a great mmp aswell… I don’t know, things like that are impossible to predict, so just use it to get ideas.
Then I basically just did this over and over again, and with each time I remembered another school, another club house, another friend who I haven’t spoken to in 15 year’s house, another football pitch, another hobby that I had forgotten that I once had… I also have filled a big radius around my house with journeys. If you don’t know how things look in atleast a 500m radius from your house, start walking or jogging and everytime choose a different path.
Ok, after that, I’ve started to make a point out of looking more closely and be more present and aware of my surroundings when I travell. I also make a point to visit more different places. With every thing that I kind of wanted to do before, there is now the added benefit of being able to extract an MMP. I have started to go to museums, so far some have been great, and some pretty boring, if it wasn’t for the fact that I will have some great material to use for MMP.
With this I managed over 50 palaces no prob, and I don’t feel like I’ve really been super active in my life, no huge social circle, not a big family either. I haven’t counted them yet. But the real number might be closer to 100. Just sit down and go through the list and don’t give up until you get atleast one more.
TL;DR: personal life history, schools, work places, friends, family, vacations, hobbies (sports, games…), utility buildings (restaurants, subways…), official buildings (museums, libraries), stores (book stores, clothes stores…) and shopping malls (Actually added a couple of extra things that weren’t in the text.)
