Now when it comes to the voice between active and passive, the active voice is most commonly used with this tone, because it doesn't require writers to sound more professional.
When I changed from a passive voice to an active voice it helped you to feel more involved like we were going to be doing this, working on this together and we are.
So go ahead and use your active voice what you usually speak with, what you usually use in an informal situation, there really isn't any need to change that.
