Have you ever told a child something that they scoffed at, and then someone else told them the same thing, and they listened? Or sat in a meeting where you've heard similar information repeatedly before, but this time the info seemed brilliant?
There are 2 factors at work here-
Sometimes we tune out people or information sources that we hear from all the time. It all becomes "blah, blah, blah.." and we don't actively pay attention. The cure for this? A new voice. Search out your information from another source. It could be another authority on the topic, a book or an online resource. If you are leading others, bring in someone else to put their twist on the information. Play a game. Create a picture. Just bring the information in a different format.
The other factor is that most people need to hear something seven times before it registers (some days I feel like it's at least 10 or 12 times!). If you have children, you can probably relate. You often don't know how many times someone has heard the same thing (including yourself). But listen enough, and most things will eventually sink in.
Do you think this means I should start re-running my posts? Or have you already noticed some running themes...?
