I am unable to focus on a single thing. I am always running from one task to another, wasting valuable time. I have tried many apps, tactics reading books, advice. None is working. I feel like I am getting dumb day by day, an asshole. What do you do maintain focus, or any drug available to increase focus and use brain?
First, block all your notifications and display only one window on your screen. Then, try to focus only 20 minutes on only one task. After that, give you a break of 10 minutes, check your email, FB, Twitter, etc. And repeat the process. It takes time, it is not always easy but with perseverance it is <i>possible</i>. When you will be comfortable with 20 minutes of focus, you will can go to 30, etc. Force yourself and you will be very satisfied with the result and it will entice you more.
