Where do you take notes, brain storm, and make your plans? Is it on your computer, tablet, or smart phone? The medium you are using could be hurting your productivity rather than helping it.
While there are lots of great tools on these devices that are designed to help you work and be productive, spending so much time on them could also lead to distractions. These devices make it really easy for your to move to something else like email, chat, Facebook, Instagram, etc.
If you are prone to lose focus to such things, try doing as much work as you can with a pen and paper. Not only will it help you to stay focused, but being able to draw out your ideas without limitations can also be really helpful to the organization of your thoughts.
