"Be kind and patient. Getting grumpy chases people away. If you
don't want to help new users then don't.
"Look for existing projects that you can join, such as a local
LUG, community computer lab, what-have-you. Going it alone can be
hard, and finding kindred spirits keeps you energized.
"Invest your time and energy into people that will pay off. In
other words, don't waste your time on people who are not receptive.
Using a well-set up computer isn't very hard for even the greenest
Linux greenpea, despite all the propaganda and FUD to the contrary.
But no matter how easy it is, there will always be people who have
mental blocks against even trying, so don't waste your time."
