I’ve never taken a break from yoyoing, ever. I will say though that I’ve never dedicated myself to playing everyday. If I had to make myself yoyo, I wouldn’t. If I were around other yoyoers things might be different.
I’ve yoyoed everyday, as far as I can remember, since I was five. I don’t play for any predetermined amount of time, I play focused and unfocused, I don’t force my yoyoing to be anything but what it is. Yoyoing isn’t my life, it just makes life better. It’s a boredom destroyer for me. I absolutely love the way yoyoing fits into my life and I wouldn’t have it any other way, though it would be nice to have a few friends to throw with on occasion.
My thought is that if you feel the need to take a break from yoyoing you really should. It will always be there when you’re ready again.
