"Si no soy yo, ¿quién? Si no es ahora, ¿cuándo?"

Simplified Meaning:

When people see something that needs to be done or a problem that needs fixing, they often wait for someone else to step in. This quote is telling us not to wait for others, but to take action ourselves. It emphasizes that if you don't do it, maybe nobody will, and if you don’t do it now, the opportunity might be lost. For example, imagine you are in a park and see some trash lying all around. You think to yourself, "Someone should clean this up." But if everyone thinks this way, the trash will stay there. Now, if you decide to pick it up yourself and do it right away, the park becomes clean quickly. In life, whether it's helping someone in need, taking initiative in a group project, or standing up for what is right, this idea pushes you to act responsibly and timely. Don’t wait for others; be the one to make the change now. This approach can lead to a more proactive and fulfilling life.
