Your knowledge evolves over time through actions in your efforts. It helps to think about your knowledge timeline and reflect on you from a perspective of before, past, present, future, and after.
The cycles of our life occur over various time horizons: day, week, month, quarter, year, and decade. I want to focus on what you can do right now in the present that enables you to share your past knowledge for yourself, family, community, and others in the future.

Before
Before your life began, knowledge was passed across generations through conversations with family and friends. However, most information was recorded by other people in books, media, and web pages on the internet. We benefit from that as we learn and grow using sources we encounter from others and make personal notes for yourself. We can do the same for our family and others now that will help them after us.
Past
Your life includes experiences, events, skills, and memories from things you did until now. Many use a PKM system with linked personal notes, which might be recorded in an Obsidian vault with your universe of ideas, which Nick Milo calls an Ideaverse for your own personal internet. Everything you did before now is in your past, and what you do after this happens in your future.
Present
You live in the present moment and apply your current knowledge on what you are doing as you focus attention and energy on specific efforts, interests, and areas of your life. You make and link notes with information and ideas that develop, extend, and enrich our personal knowledge. We have periodic practices and workflows that capture, review, plan, do (actions), log, and journal in time-based notes.
Future
When something is important or interesting, you capture, create, and connect knowledge as you make notes primarily for your own benefit and what you intend to do next. Some notes will be developed further for sharing content with others on websites, in communities, or a business. However, the focus in this series is on how you can create family notes with knowledge that will enable them to know and do after you are not available to support them.
After
What personal knowledge can you share with your family to make things easier for them after you are gone. And how can your knowledge, experience, skills, and memories benefit others too in websites, communities, or business.
Summary
This is very important for me to do for my family right now. Hopefully, my effort will also encourage you to do something that will help you too. I will be describing more details about how you can make that happen, and you can begin by following these notes that I'm sharing with you and think about what you might do.
