I can appreciate that. It can get a little hard to focus though when your mind bounces from one idea to the next. It might help to keep a list with you to jot the ideas down. You can then add each new idea to the list as it comes up. You can also add a deadline next to each one. If it isn't urgent that can help serve as a reminder that life is a marathon and not a sprint. You can then wait on non-critical items when you need to take time out for eating, self care and sleeping. Don't lose track of those items while you're being productive, ok?
