"Juega según las reglas, pero sé feroz"

Simplified Meaning:

This quote suggests that you should follow the guidelines or rules that are set but still go after what you want with a lot of energy and determination. Imagine you're playing a sport, like basketball. You should follow the rules of the game, like dribbling the ball and not fouling other players. However, while following those rules, you should also play your absolute hardest—giving it your all, running fast, jumping high, and doing everything to win. In everyday life, this could mean working hard at your job. Follow the company policies and be respectful to others, but also be very dedicated to achieving your goals. Don’t be afraid to push yourself and show your passion. This kind of attitude can help you succeed while still maintaining good conduct and respect.
