I recommend blocking all social media on your desktop browser. I use StayFocused [0] to help me do that.
On mobile, turn off all non-human notifications and alerts.
Sundays are the most productive for me. I use a weekly checklist on Taskade [1] to help me track my progress throughout the week, and on Sundays I would archive the list and start a new one from the templates.
