"باید پوست کلفت داشته باشید"

Simplified Meaning:

This saying means that to be successful or happy, you need to be able to handle criticism, negativity, and tough situations without getting upset or discouraged. Imagine you are an artist showing your paintings to others. Some people might not like your work and might say mean things about it. If you have "thick skin," you won't let their negative comments hurt your feelings. Instead, you will focus on the positive feedback and keep working on your art. In life, there will always be people who disagree with you or are not kind. Having "thick skin" helps you stay strong, keep going, and achieve your goals despite these challenges. For example, in history, Abraham Lincoln faced many critics and setbacks, but he didn't let them stop him. He stayed focused and eventually became a great president. So, having "thick skin" means staying strong and not letting negativity hold you back.
