Here is a simple, but by no means only, method of putting personal knowledge mastery into practice. It is based on the seek > sense > share model.
- Use a feed aggregator to collect all your online news and information resources in one place. I would suggest Feedly or Inoreader.
- Carry a notebook to collect insights as you go through your day. A notes application for your mobile device would work as well.
- Determine what areas you want to learn more about. Find others from whom you can learn. Identify people who share their knowledge on social media. Follow them and take notes, as above.
- Filter your online resources by marking the best in a social bookmark system like Diigo. Make sure you highlight the important part and add tags (metadata) to help with later retrieval. For long reads, save them for later on a platform like Pocket. Set up a routine to review these weekly or monthly.
- Get your notes into a retrievable form. Evernote has a system that works with Moleskine notebooks.
- Take some of what you have filtered and do something with it on a regular basis: e.g. write a review, synthesize multiple perspectives, explain how some new knowledge pertains to you or your profession.
- Put into action your new ideas by trying them out with friends or colleagues. Find a safe space (community of practice) to do this.
- Put some of your ideas and sense-making in a forum where others can find it. There is no need to advertise this. Let others find you through time.
- Once you have a body of knowledge it will be easier to find other people interested in your work. Note that whatever you use to seek and sense, ensure it is in a format that makes it easier to share later.
