Why Are Testimonials Awkward to Write?

I've been asked to write two testimonials over the past 3 days.

It took me 10 minutes to write one, and I'm struggling with the second. Why?

I'm not talking about the letter-to-head-office when you receive great service at a hotel or restaurant chain - those are straightforward and necessary.

Quick now: When did anyone present YOU to the Microsoft Board of Directors? I thought not.

So why is it so difficult to get finished?
