If your style of writing it like that - mindful of your words - writing would be a tedious job. I would suggest that you try to enjoy your writing and just write what's on your mind. Picking out the right words to say, all the time, will make you an unnatural speaker (or writer) and it's not good to have a synthetic image. Getting a potential client by proposal or invites? I guess honesty and sincerity would count a lot. Forget the specific words to write, enjoy what you are doing.
