Haz bien y no mires a quien. Do you know what it means?
Haz bien y no mires a quien is a very popular Spanish expression. Do you know what it means? Can you think of an equivalent expression in English?
Ejemplo: Haz bien y no mires a quien, incluyendo al grosero de tu jefe.
It could be something like "do it right, and don't look aside", In spanish we use it when somebody has to do something (hard, generally), and you encourage him/her to do it the right way, and don't look to anybody to check if he/her is doing it right
Could it mean? Do good works, but don't let anyone know you are doing them. Hacer buenas obras, pero no permitas que nadie sabe que está haciendo.
Do your own work to the best of your ability and don't compare yourselves with others or judge others according to your work and vice versa.
Just do something good, don't look at who it's for.
or basically, it's just saying that you should do good for anyone, it doesn't matter who.
Ok, look here
