"Tengo que ser yo."

Simplified Meaning:

When someone says "I gotta be me," they mean it's important for them to stay true to who they are and not pretend to be someone else just to please others. Imagine a girl who loves painting but feels pressured to study business because that's what her family wants. If she sticks to what she loves and pursues art, she's being true to herself. In history, think about Albert Einstein. He loved science and focused on his passions, even though people didn't always understand his ideas. He didn't give up or change his ways to fit in; instead, he stayed authentic and made huge contributions to science because he was true to himself. To apply this advice, imagine you feel like you have to act a certain way to fit in with friends or family. Instead, focus on your own interests and values. This can lead to a more fulfilling and honest life, where you surround yourself with people who appreciate you for who you really are. It helps build self-respect and happiness, as you're not constantly pretending to be someone you're not.
