With prolonged work at the computer, you may need a break to distract from work, go for a drink of water, give your eyes a rest, etc. I suggest you solve "easy" tasks: train your brain, learn to something... Also, in this way you will switch for a new problem, so after break you can continue work with a fresh mind.
not yet provided, but you can just start program from project folder with comand line: python src/main.py
