"Solo recuerda que no puedes escalar la escalera del éxito con las manos en los bolsillos."

Simplified Meaning:

If you want to achieve success, you have to put in effort and work hard. Climbing a ladder means reaching higher goals, and to do that, you need to use your hands to grab each rung and pull yourself up. Imagine someone trying to climb a ladder with their hands in their pockets; they wouldn’t be able to go very far because they’re not using their hands to help themselves. This idea is similar to doing well in school or work. For instance, if you want to get good grades, you need to study, do your homework, and pay attention in class. Similarly, at work, if you aim for a promotion or to start your own business, you need to work diligently, learn new skills, and take initiative. Therefore, success requires active effort and involvement, not just standing by and hoping for the best.
