Maybe everyone knows about messager apps, WhatsApp. This apps-owned by Mark Zuckerberg is one of most popular apps with 1 billion downloader. In this apps, I have tens active group that temporary diaturb my job. My concentration was distracted to see or comment for every single update in those group. I tried last week that not to open WhatsApp for 9 hours and I was succesfull. But this trial is not continue. I always put my mobile phone not far from my finger. I have commitment someday that I can handle my concentration and make every single target done.
