During the last weeks, I started experimenting a bit with the focus of the work.
Split your work into blocks.
The first block should be reading and communication.
You can close your Slack and email after you read all.
Put proper status so your peers will know that you are in the zone.
Do not sit too long in the zone, use the Pomodoro technique to do breaks often.
Close the focus block and then take a break for reading and communication.
Spotify can be your friend and also an enemy, the song which you do not like at the moment can distract you.
As a replacement, I can recommend mynoise.net which has a built-in Pomodoro timer.
Put your phone in a different room, and use the focus mode on your Apple Watch and MacBook to keep focus.
