Are you working from home? Make sure your office is in a specific area so you can ‘leave the office’. We all deserve downtime.
Don’t even have a room you can set aside? Buy a screen or room divider and set that up.
Maybe you’re always on the move, working mostly from your laptop. Have a token that you set up when you’re in work mode. This could be a picture of your mum or a piece of knick-knack. Whatever works for you to signify now is ‘work time’. And when you put your token away it’s time to relax!
There’s nothing wrong with playing on the computer. You can set some time aside to do that after work, so you can enjoy it. You’ll know when you’re working there’ll be time for fun stuff later on, and you can look forward to it.
Make sure you keep those boundaries for your productivity… and sanity!
