so you mean etemporaneous speaking, to be exact?

Kasi ako, i love public speaking -- as in declaiming, orating, delivering speeches -- but am not as good with extempo. Impromptu kasi eh... Thoughts are jumbled and nakaka-mental block talaga.
Read read read read (current events, novels, history, science, news, politics, etc) to have ample knowledge and thoughts so you could have a say about anything under the sun. It surely helps.
