That's definitely not universal. I play/practice music, almost every day for at least 30 minutes, and it has no influence on my life, as far as I can tell. I cannot imagine that playing the guitar for a minute has any.
It feels bizarre to claim that playing guitar for 30 minutes a day has no influence on your life. Surely it brings you joy or satisfaction or keeps your skills up if you're a professional. Why do you do it if there's no influence? Couldn't you use that time for something else?
