It’s a place where you spend almost half of your life so it might be a good idea to make it feel pleasant and comfortable.
My way to make work time enjoyable is to surround myself with flowers or plants in general. It makes me feel fresh and alive. Also, the surroundings smell nice, so thats a plus (I recommend lilies).
I like minimalism, bright colours and lots and lots of flowers, both in flowerpots and cut ones.
Here, take a look at my workspace, maybe it will inspire you to change something :)
