One of the best thing I learned is: best practices may not be your best practices. In other words know your non-profit and your audience and apply new ideas, tools, methods and best practices with that in mind.
An example would be as rule Facebook posts should be short and contain something visual. But I can long posts an entire youth story in full length with no picture and it will beat out almost any other post.
It shouldn't work, best practices tells me not to do it but for our donors and supporters they love a long youth story that does not link back to our blog.
It took me a while to be comfortable and confident enough to say that what may work for others may not be the best thing for us.
