Have you ever thought that your behaviour is determined by your personality and therefore hard to change? Maybe impossible to change?
My experience is that is may be hard to change but because of habit rather than personality. Perhaps personality has a strong dose of habit behind it.
If you are an outrageous extrovert it may be possible to stop talking and just listen. If you are a deeply quiet introvert it may be possible to inspire a group with an exciting vision.
Try breaking out of your personality box. Practice makes perfect. It’s not easy but the results will make the effort worthwhile. Personality is not an excuse.
