Some subtle differences in wording can make a huge difference in how persuasive you are and your own ability to bring your full intelligence to bear.
A simple trick is to omit the word "just", in sentences like this:
"I'm just hoping to get some feedback from you."
"I'm hoping to get some feedback from you."
The first comes across as meek, almost begging to be listened to, like a child begging a parent. The second expresses the same thought, but in the form of a request, peer to peer. The other person might agree to your request or not; either way, you're not begging.
Even better, if you want to make a request, is to express it in that form:
"Would you please give me some feedback?"
Simple but powerful.
Instead of:
"I should reply to all mail the day it comes in."
Try:
"I'd like to reply to all mail the day it comes in."
The first sentence suggests that replying to mail before close of business is a necessity that must be addressed, no matter what the cost. This throws off your ability to prioritize. Sensing that you can't really reply to all mail that way, you feel stressed because something that "should" get done won't.
The second sentence expresses an emotion or desire. It suggests that you may need to balance that desire with others. It leads you to prioritize intelligently and happily, understanding that trade-offs are what life is made of.
Be very careful in using "so". Using "so" may in fact mask the fact that your argument is not sound or has not been described in sufficient detail. Try omitting "so" and see whether the conclusion is still really obvious.
