All hilarious mocking aside (although you should probably turn this into a SaaS somehow and get it in the cloud), I've been using a simple .txt file for journaling since i started first my professional software gig in 2014.

It has gone through multiple forms, once where i created a new file everyday, and it wasnt automated much. One day I realized I could be even MORE lazy and started automating a bit. Now i have one file, with a heading for each day. I have the vim command saved as an alias now 'journal'. It opens up the file, moves to the end, and enters insert mode :p

    alias journal='vim "+normal Go" +startinsert /worklog/start_20160426'
