write in a journal

I’d like this to be more frequent for me. right now I only do it at my most desperate emotional times- very few ‘happy’ entries. I also tend to hold in entries for days at a time trying to develop the ideas more before committing to paper. then I never actually end up writing. not sure what the solution is. I should just force myself to write, but I don’t want scattered juvenile journal entries that remind me of when I was 14.
