I've found it fascinating that many of the ideas and insights that I can vividly remember being said with very few words but the powerful meaning behind them. Learning to be concise with what you're talking about is a massive skill you can develop that will help you reach more people and share information faster.
I'm unfortunately awful at this skill. I find myself in many scenarios where my words keep trailing on while not providing more value. When speaking with mentors, I would repeat myself many times and dance around the point I'm trying to make.
I need to do more research on this topic, but what I've found helpful in becoming more concise with your speech are these.
1) Be aware of origin - listen to yourself talk, either at the moment or record it, and identify where you start trailing off
2) Be intentional about getting to the point first, then add backstory if necessary
3) Don't be afraid to say little - I often think I'm not bringing enough value into what I'm saying, and so I find the need to emphasize what I'm talking about, which leads to empty words.
