"هرچه ذهن کوچکتر باشد خودپسندی بزرگتر است"

Simplified Meaning:

People with limited knowledge or understanding often think too highly of themselves. It's like how a person who knows very little about a topic might still act like an expert, showing off without realizing how much they don't know. For example, imagine someone who just learned how to play a few chords on the guitar. They might brag about their musical talent and act like they are ready to perform on stage, not recognizing that there is still so much more to learn. On the other hand, truly knowledgeable people tend to be more humble because they understand the complexities and the amount of information out there they still don’t know. To put this into practice, it's important to stay humble, keep learning, and be aware that there is always more to discover. This way, you avoid overestimating your abilities and can grow more effectively.
