With Hubgets there is no threat of being annoyed by notifications because you can mute pretty much everything :)
Of course, you can unmute Topics and people whenever you want, without missing out on anything that has happened while you were not actively listening/reading.
Time management is rarely the issue, it's mostly a side effect of the problem of delaying something to a later time, and of the stress that comes with it. We posted an interesting reading on our blog regarding the Pomodoro technique
The inventor of the Pomodoro method, author and university professor Francesco Cirillo, faced the problem of procrastination while he was teaching. His attempts to deal with this problem finally lead him to discover this simple, yet effective way that solved both the procrastination and the time management problem: The Pomodoro Technique
Hope this helps!
