Bolster Credibility by Writing
At a marketing course on how to be asked to be a guest speaker at universities, an observation was made:
If you want instant credibility, write a book.
Interesting logic, considering that many writers are people I wouldn’t necessarily want speaking at an event, or even consider credible because of their writing. For some, writing might have the opposite of the desired effect, by demonstrating their own lack of credibility.
However, for someone who does have credibility, just an inability to demonstrate that credibility, writing can provide a simple route to publicizing credibility.
First, the fact that you could come up with sufficient material for a book on a given topic shows that you have knowledge on the subject (though the quality of that knowledge would require actually reading the book).
Second, writing can help you organize your own thoughts on the subject, and help you define what it is your own expertise entails. The fact that you went through this process provides a measure of your credibility.
Having written copious amounts on this site over the past 2 years (over 400 posts and approaching 200,000 words), I considered this exercise of writing a book to be interesting, to say the least. Whether or not I choose to publish a book, the act of writing one could prove to be useful, and if ever I should need to demonstrate my credibility to someone who does not know me, I can always send them a copy of my book.
