It's not unusual to have five or six competing priorities with immediate deadlines.
To keep yourself motivated, finish something. Focus on one thing and finish it. Think about a firehose, it has a nozzle that can spread a fine mist over a large area, but that nozzle can also be focused into a single stream that blows holes in walls. Be the stream.
Research at Harvard backs it up. From The Progress Principle: Using Small Wins to Ignite Joy, Engagement, and Creativity at Work:
"People’s inner work lives seemed to lift or drag depending on whether or not their projects moved forward, even by small increments. Small wins often had a surprisingly strong positive effect, and small losses a surprisingly strong negative one."
Next week, take your list, pick a project, and finish it. Big or small, just finish it.
