Since becoming a Beach Body coach, one major key to success (DJ KHALED!) I have adopted is "Power Hour." Power Hour is a productivity tool that allows you to tackle all those random little things you never get around to.
For it to be at heightened productivity, there can be no distractions. Silence your phone, crank up the music, and get to work.
Begin by making a list of all the things you want to get done in your to do list. Be reasonable. Don't put 20 things on your to do list. Put 3-5 things, depending on how long they take. If you still have time leftover, or still have the energy to keep going then tackle the rest of the things that need to get done.
A lot of times I will designate a Power "Hour" and then keep working beyond it because I just needed the idea of that hour to get things started. If doing this daily sounds daunting, try having Power Hour once a week and see how much you can get done.
I promise if done correctly, your productivity levels will increase tenfold.
