I solved the same problem by imitating my morning and evening routine. That is, I wake up, get on my bike, and ride - but not to the city, but in the opposite direction, into the forest. I relax biking and come back home. Then my daily starts and I'm full of energy. After I'm done with all my tasks, I repeat the same procedure, just explore some different paths. When I come back home, I no longer think of my tasks.
