Trying to make this an answer rather than a comment under Weather Vane's answer…
I agree with all that Weather Vane already said, but that desk is not conducive to any work environment at all. It's too small, probably too low, you're looking out of the window, with the light behind your screen.
A laptop is a very poor substitute for a desktop & large display[s].
Losing the armrests might make you pay more attention to what you're supposed to be doing. Your chair is tilted back for relaxation, not work.
If your 'working posture' is laid back with your laptop on your knees, you've already checked out, like some early 2k's 'dotcom' with bean bags & a play area. That was a work ethic that didn't actually last.
Overall, it looks more like a student's bedroom than an office. You have nowhere to put anything. No shelving, no filing, the desk is too small to work at.
Make it into an office - even if it's only an office when you are facing the desk & can't see the rest of the room. At minimum, turn 90° clockwise so you're facing the wall, not gazing out of the window or twisting to face the open room. Sit up, don't lie back. You're approaching your day like it was a day off.
