Two phones, two computers
Your brain can't focus in the same place it goes to relax.
Picture this: you're trying to finish an important task with your kids, your friend, or your parents right next to you. It's not going to happen. You can't give them your attention and do your work properly at the same time. That's why work-life separation exists — and not just physically. It applies to every part of life.
Two phones
The first change that really helped me was splitting my phone into work and life. I had an old phone lying around unused, so I moved all my social media, leisure apps, and anything I don't use for work onto it.
Now I can keep my main phone next to me while studying — to look something up, for example — without getting pulled away by a message or an app. And using the second phone has become a deliberate choice. Picking it up to send a message or watch a video is a conscious decision. Before, I'd grab my phone without even knowing why, and within seconds I'd be lost in some distraction.
Two computers
I applied the same idea to my computer. I work at a standing desk, and that computer is for work only. No games, not even YouTube. When I'm there, I know I'm working. When I want to relax, I grab my laptop and go somewhere else to play a game, watch a video, or scroll through X.
That clear line does two things. First, it defines my work sessions. If I decide to stand at the desk for 30 minutes, an hour, or two, I know I'll be working the whole time — and when I step away, that's my time to relax. Second, I work better and more efficiently, because nothing interrupts me. Same idea as the phone.
Where in your life have you created a separation that actually works for you?
