I spend a lot of my free time learning and focusing on personal and professional goals.  As time passes it gets harder and harder to keep track of the information I digest.  I've learned to take notes for myself so my future self has a reference he can call back too.  This keeps my mind clear and ready to absorb new information in the present; knowing my notes are safely available whenever I need them.  This is a public archive or private notes. They may not help you as much as they help me; but I hope they do.
