I've quit this forum and Socionics plenty of times for months or even years and I just ended up going to other forums that were even more addictive. So I think this place and Socionics is not too bad as long as you don't look at it religiously. Taking it all with a grain of salt is what I learned from leaving this place.
Having the Socionics filter on in everyday life can be fun, but it can also be very disappointing if you don't realize that it's just a filter that alters your perception of others around you. Socionics is a perspective with some basis on reality, but it is limited in scope so it should not be taken too seriously.
