My home is entirely decorated with knick knacks that are personal to us. Things we found on the ground, or shit from concerts or whatever. Photos on walls are all just silly pictures we took throughout the years, no professional photography shit. All lamps and things are unique and either bought at a thrift shop or found or handed down. Same with furniture, just whatever we've had or got from someone or whatever. Anyone who has been to my house always spends some time looking around at things and asking what is this and we always have a story behind it. Never, "bought it at the mall" same with our pictures. We have hundreds of photos all of which have a story behind them and each in a unique frame we found somewhere or bought in a garage sale or something.
Long story short, I'm with you and I hate soulless homes. 99% of the house I go in are just cookie cutter bullshit with zero personality.
