> write these things down in a journal

My added 2 cents is to write in a journal and also to read it.

If it helps, be meta and write about what you would want to look forward to read in your own journal, what kind of writing makes you keep going back reading it.

Certainly, an awesome evergreen entry is your reflection on a previous entry.

Just like material on how to blog, there are self-help books on how to journal well.

Solitude doesn't have to be a curse if we learn how to treat it as a blessing.
