Don't rush! Impatient people can't accomplish great things.
Tips
usage
急性子 describes both the trait and the person: 他是急性子 (he is an impatient type). It is more informal and colourful than 急躁 (impetuous, irritable), which is purely adjectival. Contrast with 慢性子 (mànxìngzi) — a slow, unhurried person.
