When you are full of knowledge and can export it in writing, this is your talent. Ambition means your future goals, your ideals in life, or the dreams you want to realize. If you want to realize your dream, you need to calm down and study. When your talent cannot support your ambition, you should calm down and study. This sentence means to harm you, to put pressure on you to grow, and to inspire you. That’s enough detail! Thanks.
