Do you ever find yourself sitting down to work on a project for your job，study for an important test，or even just get some simple things done，but find yourself almost immediately caught in social media for hours at a time？While providing plenty of fun，social media can，unfortunately，stop us from focusing on business.
   Losing focus can be a result of a distracting environment—not preparing yourself mentally for your work，or not having the right systems in place to make sure you stay on task.Luckily，focusing is something we can learn and practise.There are many simple things you can do right away to start seeing results.
   First，prepare by writing out your to do list the night before.If you know you're going to need to focus for a long period of time the next day，take a few minutes to write down a list of all the tasks that you want to complete.Make sure this list is as specific as possible.For example，instead of simply writing down "study Spanish"，write down something like "memorize 20 Spanish words".
   Next，make sure you get enough sleep.Poor sleep can make it difficult to complete anything.Your mind doesn't have the energy it needs for long periods of focus.If you really have to focus on a project even though you're running on low sleep，try taking 10-minute naps in-between tasks so you can start to get back some of your energy.
   Your environment is also important when it comes to helping you focus.More outgoing people may focus well in a coffee shop with other people around.While others may prefer the quiet of their home office.Have a clean workspace.Remove any projects or items that don't have to do with what you're immediately working on.Perhaps most importantly：turn off your phone and place it in another room.Like they always say： "Out of sight，out of mind."
   Keep working on focusing for extended periods of time，and you'll eventually work your way up to be able to focus for quite a long time.Just remember that focusing for too long isn't always the best idea.Take breaks，stay healthy，and you'll find yourself focusing like a doctor in operation.
