I used "Trust me" in a blog post http://visualwebsiteoptimizer.com/split-testing-blog/debunki... and my friend quickly reminded me that it is a cliche and usually doesn't add much value to the argument. Ideally, your argument should be so strong that it doesn't require an explicit reminder for readers to trust you.
We only have a bunch of things going on for us. Happiness, Love, Adventure, Sadness and Loneliness. But would you rather not be happy because it is cliche. Emotion is cliche and so is cliche. The above post was not to appeal to your logical sense but rather to intuition. So I don't really have a case as to why you should trust me. In fact that part was to inspire some stupidity. The line between stupidity and adventure is a very thin one. Find yours. I will just stand out here on the stupid side and shout out some encouragement. Thats all.
