Give away all your knowledge for free with no expectation.
I firmly believe that we all should be giving away our knowledge for free. You can do that in the form of videos and blogs. It is a great way to help out as many folks as possible, there are so many folks that are struggling with so many things, things that you have skills with and others would like to learn.
Lots of folks are afraid but, what you actually will do is attract people to you and your skills.
