Pag may tiyaga, may nilaga.
Which translates to:
If you persevere, you will reap the fruits of your labor.
They don't call them the fruits of labor for nothing. Hard work and perseverance are needed to reach your goals. But if you keep trying, one day you will enjoy the results of your efforts.
I believe this saying is said in every language and culture, definitely a fact and something to follow EACH AND EVERYDAY.
