Many people can't do their jobs without a computer screen. But if you need to type up your work, it may help to put your thoughts on paper before opening up a document. Working analog in the brainstorming stage can help you think through your ideas freely and clearly.
Having a handwritten approach can also help you stay organised offline. Investing in a nice planner or committing to bullet journaling helps you be productive even without your computer or a phone at hand.
