Right now I have a fav digital tool and fav analog tool for writing.
For digital it's using a meditation timer set for 30 minutes. Sometimes it can feel a bit overwhelming to start a post or get back into one. Setting a timer helps get things moving. Here's one I use:
For analog it's a fountain pen. I've been writing in a journal every day for years. Finding a pen that feels smooth and works well both literally and figuratively helps the creativity flow. Recently I picked up the Pilot Metropolitan pen. I've never used a fountain pen before, and this has felt pretty good.
