how to finally be productive.

Productivity comes from showing up and trying your best, not achieving perfection. Reset your standards to view imperfection as acceptable—the only failure is never starting. Avoid comparison with others and accept that progress isn't linear. Two approaches help: training discipline in any area (which transfers to work) or recreating past motivated states by replicating the environment. A practical technique involves writing freely on paper to identify task-avoidance reasons, visualizing the work atmosphere, setting it up without committing to work, then staring at the screen in 5-minute intervals until boredom drives you to start.
