Hi all, I wanted to know: have any of you ever sabotaged how quickly you could possibly "understand" a concept in physics by assuming that it would take a long time before you even began reading about it? Then, you read about it, and it's simple after all? Only...you were prejudiced to expecting hours of fruitless staring, and it turned out that wasn't necessary at all, and you understand the concept in five minutes? It happens to me all the time: and I waste hours of staring that way. Any suggestions on how to overcome that?
