>Long time ago in the back of my head, i remember someone telling me something about you having to practice your skill (in this case, art) for the entirety of the day, no gaming, no socializing (only when speaking with an artist for feedback and guidance), and no toilet break either, only practice

I can't remember much of the details other than this, but the question is, what's the most ideal time for practicing? Should i practice for 100 hours? Should i practice during my fasting hour? Should i practice after weightlifting? I need to know.
