This phrase is used to express that those who take on many tasks or responsibilities often accomplish less, as they can't focus on everything at once. It's similar to the English saying, 'Jack of all trades, master of none.'
Examples
- Spanish: No puedes ser presidente del club de ajedrez, estrella del equipo de fútbol y además tener las mejores notas de la clase. Recuerda, el que mucho abarca, poco aprieta.
- English: You can't be the president of the chess club, the star of the football team, and also have the best grades in the class. Remember, he who covers a lot, squeezes little.
