Your ability to focus and properly allocate your time is instrumental to any success that you hope to achieve. However, the world, and specifically the internet, is not designed to help you focus. It is design to grab your attention with a compelling headline and suck you away from whatever you are working on to read some trivial piece of information that has nothing to do with your dreams, hopes and fears.
There is no special cure for managing your distractions. There is no special app, no browser plugin, and no list of "The Top 10 Ways To..." that the world can ever give you that will help you be less distraction.
Focus and concentration are a choice. Choose to focus and win the attention game.
I dare you to watch this video for the next 180 seconds and do nothing else.
Do not pick up your phone. Do not move your mouse. Do not touch your keyboard. Use this as a simple exercise in concentration. Even I had a hard time doing it. But if you can do it, you'll start to understand the kind of focus that you will need to get other things done. Enjoy.
