Mental Tetris is a personal development blog geared toward clearing my mental clutter and synthesizing many different tools, frameworks and philosophies into crisp, actionable and bullshit-proof methods to improve your mind. Bonus bad humor. 😛

This is a place where I distill and chunk what I’ve learned and tried regarding thinking, decision making, habits, productivity,  performance improvement and more. I’m sharing it with hope that it will help you and clear up some mental space. Just like clearing a line in tetris.


Hi, I’m Kristijan. By day, I’m an ordinary R&D Engineer in the fields of Machine Learning and Computer Vision. But by night, I’m… totally asleep. I love to explore ways to improve myself physically, mentally and emotionally. Funky belief systems are my particular weakness. I am obsessed with metacognition and metalearning.
