Any question answered...

Thanks guys, very helpful

The reason I was going to go for transformat* over 'life-changing' is that the former sounds more active to my ear, where as the latter sounds more passive. Moreover, 'life-changing' seems even more hackneyed than transformat*.

For now I will just pick one to use for now, then adjust according to cadence on the final read.

Mattty, I've written a shit load of letters of intent. I'd be happy to pass one on to you, if you'd like?

I appreciate the offer, but this is a response to a specific question, rather than a letter of intent.
