Educators all over the world have known for a very long time that one of the best methods of learning something is to teach it to another person. This is the reason teachers made you do presentations to the rest of the class when you were in school; they were hoping that by teaching something to your peers, you would get more out of the assignment.
The same principle can still be applied today when you take your newly learned knowledge and skills and share them with someone else. You can start by translating the information into your own words; this process alone can actually help your brain solidify the information. The next step is to find a way of sharing with others what you have just learned. There are numerous methods of doing this; you could write a post to your blog, participate in a group discussion or create a podcast.
