"Cuanto más viajaba más me daba cuenta de que el miedo convierte en extraños a personas que deberían ser amigas."

Simplified Meaning:

When you travel and meet new people, you start to understand that many of the people we are scared of could actually be our friends. This fear often comes from not knowing them well or from different backgrounds or cultures. For example, let's say you go to a new school and see a group of students who look different from you or speak another language. At first, you might feel afraid or unsure about talking to them. But when you finally get to know them, you find out they have similar interests, enjoy the same games, or have big hearts. Fear can keep us from connecting, making us think that someone we don't know is too different or even dangerous. If we push past that fear and try to understand and communicate, we often find that there's no reason to be scared and that those people could become good friends. So, the advice here is to try and be open-minded. When you meet someone new, don't let fear stop you from getting to know them; you might end up finding a friend you wouldn't have expected.
