Think outside the box, don't throw suggestions roughly but draft them properly and make an honest effort for it to be discussion-worthy.
Break things down to bullet points, tackle them one by one. If you are using data then add a source, if you are examining someone's results then look at the references they have, see if that indeed happened, and if it could be avoided. Don't just throw comments vaguely in the air just because you feel a sense of authority.
When you are wise, the weight on your shoulders to make a wise decision becomes very heavy. If it's not then you got to rethink if you're thinking it through.
