Quit social media hardcore. Block every distraction. Build systems, and stick to them.

Forget "motivation". Motivation is not practical. You must remove distractions.

Use Cold Turkey Blocker, turn off your phone and leave it inside a drawer, uninstall video games, delete every social media app.

Eliminate every cue that makes you procrastinate.

This is the ONLY thing that worked for me in over 6 years of trying to fix procrastination.

Without distractions, you can only work. Then work eventually becomes interesting.
