A personal statement usually has between three and five paragraphs. Each paragraph has a main idea that is supported by specific details.
If your main idea is that you have been inspired to apply for the course by talks and lectures you have listened to, your claim (that you have been inspired) will be backed by the names of the speakers and their talks, and at least one example of an inspiring point that was made in each talk. Simply stating names, or name dropping, proves nothing, so always supply the specific details.
