I think this sums it up for you perfectly. If it feels pointless and drives you insane then giving it up is for the best. If when you step back you realize the toys aren't that important to you then they probably never were in the first place. If the only toys you truly covet come from lotteries maybe you are more interested in the exclusiveness than you are in the actual toys. For a lot of us toys are the form of art we collect. I believe wholeheartedly that everyone should collect art. Every single person. Doesn't matter if it's posters or movies or stickers or books or comics or stamps or toys or ceramic dishware. We all need art in our lives. Luckily most art is easier to get than sofubi. Lots of it is cheaper too! As far as sofubi goes I've entered well over three hundred lotteries in the past decade and won maybe 20 of them. Not once have I ever gotten upset that I lost. Or felt like the system was unfairly rigged against me. Or got mad at others who won. Those reactions have less to do with sofubi and more to do with the kind of person you are.
