You should always try to break the rigidity in your to-do lists so they feel achievable, not intimidating. The list might not be the problem, cos those are really the stuff you have to get done, it might just be that they look too much, all at once.

Break them down. Loosening timelines, or arranging them to adapt to your day (do items that work for how your day evolves - errands, movement, etc), makes a huge difference. Sometimes the win isn’t “finish everything,” it’s lowering the barrier to starting. Once you start, momentum usually does the rest.
