Quantity tells you “how much.” If you're concerned with quantity not quality, it's more important how many you have than how good they are.

If you get confused about quantity vs. quality, remember that quant is close to count. In Latin, quantus means “how great” or “how much.” When you count how many oranges are in a bowl, you know the quantity. When you count the grains of sand in a desert, you're counting a very large quantity . . . and you need a new hobby.
