"Don't be defined by difficulties" means don't let difficulties become the main factor in your self-description and self-understanding.

In daily life, we often encounter various difficulties and challenges, such as work problems, interpersonal problems, financial troubles, etc. If we allow these difficulties to define us, we will feel like a worthless person who is incapable of solving problems.

On the contrary, we should see ourselves not just as victims of difficulties, but as people who can overcome them. Difficulties are a part of life that everyone encounters, and how we face and overcome them is what truly determines who we are. Therefore, don't be defined by difficulties, but see your potential and abilities and believe that you can overcome any difficulties and become a better version of yourself.
