Omo! I can relate to this because we tend to be carried away with lots of things. When we decide to start on something, there comes a distraction that takes us away completely, then another, and another, and before we know it, time is gone. What we intend to do at first has been tampered with and no time.
This is why when writing a post, I disabled my notification till I am done because if I don't, I might not be able to complete it.
Hmm, yes oo. Seems I'll join you in disabling notifications when I want to write. One thing I started doing was using earphones and listening to Lofi music while writing. Its helped a bit, but at times I just don't want to be listening to music while writing.
