Answer: "I am sorry that I won't be able to say everything I'd planned in my remaining time, but please let me conclude with . . ." Then state your most important idea and make your conclusion before time runs out.
Explanation: If you may be cut off by the moderator or the chairman, your audience will at least hear the conclusion you planned. If you are stopped ( and it DOES happen ) in mid-sentence or without making your most important point, the audience will see you as disorganized, or insensitive to the time limits, and may have an unfavorable impression of you-- and they will have missed the purpose of your speech.
To be brave means to continue to fight for what you believe and pursue your dreams in the face of opposition, trials and even threats to life.
For example, In Malala's speech, she said, "Dear Friends, on the 9th of October 2012, the Taliban shot me on the left side of my forehead. They shot my friends too. They thought that the bullets would silence us. But they failed. And then, out of that silence came, thousands of voices. The terrorists thought that they would change our aims and stop our ambitions but nothing changed in my life except this: Weakness, fear and hopelessness died. Strength, power and courage was born. I am the same Malala. My ambitions are the same. My hopes are the same. My dreams are the same."
This means that she has dedicated her life to preaching peace, education, human right and equality, not minding her own insecurity or whatever persecution she faces for what she believes. This is her definition of bravery, boldness and courage.
