It is a good thing to practice more direct language. This means to focus clearly on what you want and spell it out in the fewest words possible. Some tips to try:
Replace ‘Could you help me’ with ‘Would you help me?’. Doing this will invoke very different response from people.
Practice statements without follow-on ‘tag’ questions, like ‘don’t you think?’ or “Isn’t it?’
Think about how to state things more directly. For example;
‘I don’t think we have talked about this enough’ becomes ‘would you schedule a meeting so we can discuss this in more detail?’
‘Sorry, I don’t think this is going to work’ becomes ‘I have considered the idea and I am not interested in pursuing it’
‘I don’t have time to finish this and I think I need some help’ becomes ‘Would you handle the completion of this proposal?’
Focusing on what you want makes direct language easier. Or is it the other way around?
