It absolutely can work for task initiation. It's less effective for maintaining momentum, but initiating a task is often all people need to resume being productive.
I remember watching Rambo 2 (or maybe it was Rambo 3) as a young kid, and it motivated me so much that, in the middle of the movie, I ran to my room, grabbed some weights, and started working out. A few months later... just kidding. I didn’t keep working out after the movie ended. But, but! It did push me to do something!
Guys often work out twice as hard when there’s an attractive woman nearby.
Whatever works. My job is to help people overcome chronic procrastination, and I’ve seen how motivational videos can help those who struggle with task initiation.
The problem is that watching a video is a task in itself, and people who procrastinate might struggle with even something that simple (I’m one of them). Keeping the video in an open tab might be a good idea.
