Finding focus allows you to work smarter and get your tasks done sooner, so you can take more breaks and live a more balanced life.
Changing locations can be a great way to get over an afternoon slump. Set a task and head to a cafe, or even just a different place in the office, to get it done.
Focus looks different for everyone. Try out different techniques and/or apps until you find that thing that helps you get in your groove.
Don’t use lack of focus as an excuse. Time is precious so make use of it the best you can. If you’re commuting, for example, try writing on your phone or listening to an educational podcast to make use of the time.
