I once heard something amazing from a rebbe of mine. He once worked in a school where the bochrim were known for wearing colored shirts (often untucked). He asked the art teacher if he’d get each bochur to draw a picture of “someone learning Torah”. The art teacher did this, and gave the pictures to the Rebbe.
Each bochur drew a picture of someone in a hat and jacket, well groomed. This rebbe then told his bochrim this is why you have trouble learning. You have this perception of who it is who learns torah, and you don’t feel that you fit into this perception that you have in your heads. Every Yid has the ability to learn, and a white shirt, black jacket and a hat are not a prerequisite for limud Torah.
