"El que siempre cede a los demás terminará sin tener principios propios."

Simplified Meaning:

If a person always lets others tell them what to do and never stands up for their own beliefs, they will end up not having their own opinions or standards. Think of someone who constantly agrees with their friends, even if deep down they feel differently. Over time, this person might forget what they truly believe in and just go along with whatever others say. For example, if a student always copies answers from classmates to fit in, they won’t develop their own thinking skills or knowledge. It's important for people to trust themselves and stand firm on their values, so they don’t lose sight of who they are and what they believe in. By balancing respect for others with a strong sense of self, they can build a life that feels true to them.
