I used to think I enjoyed chess for a while, back when I just messed around playing against my sister and complete novice friends. Then I played against someone who actually played seriously, studied the game and knew a bunch of stuff and I realized how big a difference there was there. Also realized I would never be arsed to put in the dedication to even start getting better and figured I’ll just stick to video games. : )
