I keep chanting Hare krishna mahamantra in my mind or by saying whenever I am alone or doing anything.

Hare krishna hare krishna, krishna krishna hare hare, hare ram ram, ram ram hare hare. This is what goes on my mind most of the time, no matter I am watching a movie, eating, sleeping, driving, doing anything we do in our lives. And 2 days ago in my sleep (sapne me) also I was saying this. I read gita since jan 2022 regularly (maybe miss a day or two under different circumstances) am I doing it too much ? I am a family man and have responsibilities also. Need some guidance on whether it’s a good practice or not. I don’t have any guru.
