The moment the screen brakes, that's when I change it, so not very often. My last phone lasted 2-3 years, I guess, before it's outer screen broke and the plasma of the inner one exploded in multiple colours all around.
Where I put my phone last. I'm always moving around the house with my phone, but then I'd drop it somewhere to grab something and then forget where I put it.
No matter what happens or what I do during the day, I'm always scared, worse yet, terrified. I'm always drowning in the fear of dying any second of the day without accomplishing everything on my mind and leaving the world with unfinished business, and goals yet in the process of becoming true. I don't know about everyone, but this piece of unknown truth terrifies me everyday and night. That's what keeps me going, that's what stops me from quiting.
